06-24-2015 Leap Second In Halacha

hello and welcome to stargaze monthly webinar we're here in the staircase of offices in Baltimore Maryland I want me to Goldberg your host and today we're pleased to have relative of ever journey with us say thank you thank you for coming over ever thank you for having me up these webinars I held the last ones every each month and they are archived on the vimeo you can look on the vimeo search for star k webinars and you should be able to find them you can also call in if you would like I'll give you the phone number it's 218 895 1203 again 218 895 1203 pass code 2020 and I want to thank in advance our tech support Robert Rubin Chapman miss Debbie Rosenstein for their continued assistance so today we're going to talk about the leap second grabbing ever but which I didn't know too much about before we before we looked into into doing this but you know the gamar says that that you start we start with it with a light comment a joke sometimes right so is this there is a a joke about a certain shul that was very careful about starting on time and they have always would start to the minyanim exactly all the time so the closet goes up and he looks at the clock he sees it says ten o'clock so he turns to the gaba and he says is it time we got my says no now so or is they gotta do it exactly on time um so there is a there is a lot I think there's some interest about this leap second like what it was all about and what is what is the meaning first from a we'll talk about first from a astronomical perspective what is it and secondly from a locking perspective I should mention that rubbish ever is as we to the email or whatever is a is an expert on smilin on Jewish time and in time in Jewish law and he has written his safer called shari's mono and it's available at at rotate what's the name of the round robin love is i think right it's a caress tribulus distributed or specific send some distributors it's a some bookstores mr. the by rubble of its around a chap and keep at this number down there for the safer 718 3770 377 00 47 so I noticed i we have it looking around it is like some consternation about this it's next week next tuesday right all right and uh the stock market is worried about it they may they may they're worried they may crash well actually if it should be close by that because it's been it's a minute it's a second before midnight and greenwich time so that would be five hours here so be seven o'clock at night so in other words would be well off our show if you don't notice how we're training this off I'm training I'm not sure exactly what but some of it some of the markets are closing during that time because they're free of some little glitches yeah so let's start at the beginning which is what is a leap second about and why do we need it and sure okay so people think of time of course seconds there are 60 seconds of minutes if Vincent now or we all know that 24 hours in a day so if you break it down it takes 24 hours for a day which means the Sun will rise in the morning at 24 hours later it'll rise again as we all know it's not exactly 24 hours later but on average if you take an average over the course of the year sometimes it summarizes 1 24 hours later something less but if over the course of the year the day time takes the sunrise to come is 24 hours if you break that down into different parts to see in a day you have 86,400 seconds 60 seconds 10 minutes 15 minutes on etc however the Earth has the rotation of the earth has irregularities in the rotation therefore that you know number of years back as science became more of technology gruel and and you know these these executives became were more known to scientists they realize it that this this average little made a little bit off so they redefine a second based on um it's known you've heard the term atomic clock the time of clocks what is it type of clock what does that mean what is atomic about o'clock so the answer is it's precise and it's based on certain cycles and frequencies of cesium atom and radiation that's released it's a certain number given nine billion hundred ninety two million 630 1770 so so you take that number that's a certain number of a number of of the frequency of this annum and when that when that happens that many times that's a second I see okay so that's the scientific stuff which is beyond my exactly what's happening i typically lobby things to happen in one physicist well you know look at a lot of atoms in this you know and you're figuring it also this okay it's unbelievable then the plus i by ray of to punish a lot of attachments it calculate some really you know fraction literally billions of a is going to make a difference to billions of this anyway so it was sort of redefine that it was made it's called more precise but what happens is over time the Earth's because these irregularities in the earth etc they need to get it back on track so that it's everything's back soon as you say recognized right it's you calculate everything out and you make the calculations if you see that there's a variation periodically and hence they in order to to get it back on track they add a second periodically this will be the 26th a leap second that's been added it's typically added the last second of the year in december 31st but also it could be done so they're trying to get it in sync with the earth rotation then what happened then which I understand so but i read that they started in 1977 sup like that so what happens the first 5,000 years old off in other words i mean how do we exist somehow we have a problem so what happened in 1977 that they decided that we gotta add a few seconds the answer is and why don't they had 20 seconds or anything they didn't they didn't it didn't matter so to speak and ultimately really the scope of it over thousands of years doesn't really make a difference now what happens is because because of so many so much technology every second right as such a you know when you're dealing on the scope of of you know satellites which work you know literally to the nanosecond everything has to be has to be sink streaming it's sick but I put up on the screen over heaven was a screenshot from the last leap second which was three years ago so you can see the oddity of it it says 23 59 and 60 seconds there isn't no there isn't any 60 seconds it should be 20 20 20 for it should desireless the februari 20 what should be zapped and that's not even 24 it should be it should be the next day when should be around would be all what exactly right ready Sunday so it really is electro srija Lee is the next day so they added it that's that's the leap second there they took a picture of the video that's what the screenshot is but I saw also that there are different ways of dealing with it some computer why some will add another second some will just stop stop the clock for a second and some will extend the seconds the first the last couple seconds before partially they'll be extended to me or say a third of a second longer and then as I took 33 seconds of the third second has up to a second so different ways of dealing with it from a computer perspective I want to mention that we do have a chat box here if anybody has any questions for everybody ever so feel free to chat with us i'm going to bring that up right now so feel free to chat here on the bottom we'll try to take your questions okay so that's in a nutshell what is what they leap take out what's what is trying to do but ok let's took let's move on to the office of it help us hellz no sleep secular well technically speaking because it's such a small amount of time we practically speaking for example if you're looking at a madam we usually don't leave things to the last second anyway in other words if you're feeling it sighs my Priya shmeh for example the next day of any blew up and if you can get it to the second which I'll tell you why that's not such a good idea wait for that second mysa technically only one second off because all that is to get back at the sink once you add a second just like much about the Redeemer if you use a sunrise sunset charcoal Navy charts that were used for every year technically if you had a march first coming after februari 29th those times were varied because some museum fairly 29 some years he did so if you had a favorite of 29 you look at this man IM of march first for that matter the whole year it's going to be the sunrise sunset could be different a march first after fibia 29 ok don't think out different charts for their well now now in the more sophisticated where we live in there tries to come out for every year but the Naval Observatory which is what you know what as a kid you know we grew up with those charts I didn't grow up against guys maybe you didn't know okay there were few they were that we're ready now when I was a kid to work computer generated charts but not really to the second and they were hard to find for you know every year a new one that's relatively new thing but my set again practically speaking this not really such a knife Camino because no one should wait to the last second sacrus mad because it's not a good idea Seconal you can't get it done by then in a second and most important even charts that give you to the second are not exact because let's say talk about sunrise and the reason for that is when you look at a chart of sunrise and sunset to the second there are various factors that could change that including the weather of the barometric pressure and so on is no way to sit here no way for me to tell you right now definitively when sunset will be tonight in Baltimore Maryland to the second there's no way to know pretty much until you figure out the weather conditions that are going on at that point of course even even altitude Kevin have an impact which is a really separate issue but we then I got calls you know baby was born sign hospital which is the hospital many children and from from families use in Baltimore and they had a baby right at the Shia and now the question is once the bris is it let's say it would be today was the bris gonna be next week on wednesday or thursday and we sat and you know their two resident experts in town that commits calculations fish kind and belly ride learn and we sat on the phone analyzing exactly where sign hospital is what the weather conditions were to try to get to the second as to when she Kia was in order to determine that it was so close anyway you should anyway it was born five secs before your calculator kiya this down a matter like 40 seconds why'd you have to make sure you ever think you know was was there then you really have to avoid his that says that 300 years ago there was no way anyone could have known exactly when sunset and sunrise i was all approximations while he watched our associate actually watch notice it a calculated paper it was much harder in those days in a way it was easier because they weren't such tall buildings and therefore you just go outside when they say the diamond at nates hammer days victim ro we have to assume that they had those who diaz really go outside and it was a natural phenomenon unlike today you know I when I'm out driving somewhere middle nowhere at a time the biggest thrills to try to kind of exactly when that Sun dipped and then if I'm able to know exactly where I was at this rare I could do this but you know make the calculations that I actually saw the truce on son huh okay that's rare so this is so the short term there is no real difference for a second correct what about long-term of a period of time they said is 25 there's been 25 seconds right that's right we look 16 exact would that make a difference it's actually when I wrote the safer saw it I tried to come up with I haven't checked out of Paragon kiddush levanah my latest I'm sickish levantas and the earliest i'm sitting on them now drama says the latest I'm sickish lavonda is halfway between one mile in the next in other words basically until the moment the moon comes full it's the latest time you could take your chiffon actually remind everybody a lot of places for cloudy this week what's the showers all right people shouldn't say Kesha Fonda one day when they have opportunity to do so what do you mean it was cloudy I just as my job my cities cost anyway what is absolute past the latest possible moment to say kiddush levana staff over to a mile in one mile of the next now the time of the muddula that's given is the time of fish align and assumes the our bias and more specific the mahkum kozhikode that's the Shaam eyelid when they give that time the mullet is enough is an astronomical event when the when the moon is between the Earth and the Sun and they're aligned sometimes a little higher or lower eclipse but it's good being eclipsed upon which is a whole other discussion but they're all online and at that moment when they're aligned what is on average what is the time on electric now over time so so when is that and how do you make those calculations so over time the clocks have been changed which have been practical enough commune is the difference in a lotta which maybe we'll talk about a little bit later but for example standard time was it change in you shall I and change their time 21 minutes they turn their clock 21 minutes to facilitate what we call standard time which means the whole the whole stands at times W Schleim is in is two hours later than England seven hours later than America the time to Baltimore example in a day or so they added 21 minutes they actually at one day when it was 12 21 approximately actually 12 22 56 seconds they turned their clocks back when was it I don't leash landed in America it was done I believe I'm in 1883 the railroads actually called for this to in order to because we all wrote were different times was a lot of confusion New York have different times in Baltimore Boston Philly New York baltimore-washington all at different times it was a different time and any given moment was right now it's 12 16 p.m. eastern standard time issues daylight savings time he's the daylight time but but that's all because we all turned our clocks on my 18th 1883 so that the whole East Coast for that matter always did time zone was it sick and that's the way it's remained some some of the time zone has been changed a little bit subsidies have flipped from you know one to the other basically we have the same four time zones since since 1883 it was it was mayor no fabric stuff which one was made was november eight is right either way it was it was a it was eighteen eighty-three now every stall also made that change so that's one different status or ramification on according to many shooters secular slavonic because if we tampered with the clock anyway to make a long story short one of the things i discussed is does in my original version of the safer i wrote that you have to change it by when i would say it was only 23 seconds but now will be 26 seconds this seismic additional phone has to be modified with 26 seconds because of the change now practically speaking who's waiting for the last 26 seconds in kosovo know right you know not do you mean what the time like that they announced well though always announce the model they announcing them up but it coming for the end from there from there when you go from there how much do you add together to use the one you have to have 26 seconds that's what you say as we wrote a personal check we will you deduct what is appetizing so so someone actually i got two letters from from people who run safer explaining that null that if I carrot the opposite is true because the real time is the leap second is fixing the Kenneth Clark the fact that it got off is was wrong nose had it not been for the leap second that have to modify it by the 26 seconds because it's odd today were correcting it and now it's the correct time so that's correct right so I ain't got a little research on this exactly when you say the myelin which one is it using is it you know the solvent have the cesium atom to wrestle it's a Howard there was a worthy regular is their sudden and I was Pacific so what am I read every published is safe for really only electronically and we're number of errors in the air numbers were off there were some typos etc some fish minus we're outside redid it and corrected those and actually we put it was put up on new books that work where the safe was available and in there I changed that as a blanket statement to more of tardy in saying that what impact was this leap second half on the exact time of the service mikonos a maybe can it might not now might be correct where beforehand it was incorrect not very good okay um okay we have a few comments over here Adam wants to talk more about the the birth when they count the birth and only met for it for afterwards you can count I grab a hammer for that pinterest says I don't know whether it was november November's it yeah okay they switched to a new standard time right correct on the vibrator that make it so you mentioned you mentioned while he was talking about ever that that about the hair advice about the Temple Mount and the color code ocean the Holy of Holies that's that's weird could explain how that fits into the right correct if we're saying that every place really is a different time based on your location and you know Baltimore Philadelphia actually Baltimore changed to stay on the time which was a line running through basically facili Philadelphia little bit sort of the east part so everyone change so when you're dealing with the middle of time that is dealing that with with the stand of time but it was it's telling you that the solar time of your schlong Iraq Eilish namely than our bias so I tried to calculate exactly it coming up insects and fish lavona i calculated exactly the heart bias and that's going to be really the basis of two things number one shasa milos for that place so if you want to know that we have them all that we announce ensure her every month is in your shall I'm that that much I think that's the time of you it's a time in your time on average of when these you know the Sun Moon and Earth or a line which is the chatham I delivered my load means renew rid of Burt born the moon gets smaller smaller smaller this is split second where they're aligned and this split-second at less than the split second later it all happens it goes to zero and then starts again so that's a mileage so what does it have to do with the Kodiak reduction exactly so we're just saying that the way that the time of the my lad would be when you say the my love is that you know 2 p.m. this coming Wednesday let's say or this coming good whatever the time we'll announce that is the solar time at the credit record a shimmer you know on average at the concert reduction that's that's that's the time at therefore that's your starting point and now if you want to calculate standard time you have to take that point and see how much off the stand a timeline it is so again Baltimore's to Philadelphia did it eastern time zone is based on 75 degrees west of grunge Grandage of course is the line that runs through an observatory in an inland eric's easter all goes with two hours east of of greenwich so therefore that's a lie that I believe runs through Egypt somewhere so Eric Staal changed o'clock how much you change your clock depends on how far east view are from that line the more east you get the more you change your clock so main you know Eastport Maine and van buren Maine which are the eastern parts of Maine change their clock you know a lot on that stand the time they Baltimore change by about 6 minutes north dakota the west north western part of North Dakota change a clock at 59 minutes because they were literally an hour off said he would say that technique a labels attached by that point on our bias is critical so also an issue that came up you know where's our bias exactly so that's actually very thing that so commonly known there's actually pointed out to me after all so let's say after that safer and that is there's a must like as we shine them as to where on our maps where the current election was and it has enough for me and I'll tell awesome in a moment related to the international date line as well but the standard you know if you ask the average person in the street or they ever tour guide there are bias they will tell you that of course where the doggone right right right at places where the petrol collection was so that is the opinion of the of the rod vas right and that's the classic place now it's far so therefore an annual you'll change your clock from that point on if you go into the tunnel tours in by the cocoa I think there's a sign there they'll tell you like this right away right how can they are placed in their special place people go to daven right exactly but how far in is it that's dumb interactor is um there is a website of someone who actually mapped all the international Dateline's but all opinions based on these are based it on this it's the java if you google java and a line you know hahaha look at the forgot the exact name of the website but you get a map that shows you weird our biases where the all the deadlines are which again is going to be for example the ostentatious bait line is where shabbos you know nothing because the chances give me exactly one quarter of the globe east of you shal i am which is 90 degrees or six hours east of your shall i'm nowhere so you start with our bias the right doc is of the opinion that the mahkumat mcdouche was really the Dome of the rock is where them is bath one of them was bath was which means that the Quecha kardashian is really about 180 feet to the west of at that point you have enough kamina of 180 feet now now if you're normally hundred eighty feet doesn't I mean I'm just trying to remember according to the housing ish the dateline doesn't go through correct some land mass in Larry so we talked to the correct inhale mascara fauna this is maybe a tenth of a second quarter sex is no real time laughing minute but I did find this voice this afternoon's a discussion actually a practical left me la-la we're between the ref on sunday where our dynamic dishes as an island in the philippines if you look at a map you'll see the fascinations line which again is a quarter of the globe east of of fish line now just just to explain more point it has any child that based on the site islands were tama to rush through the rush that the dateline cannot run through land and if it would you think of the practical mean as you'd be shyness would be here and you know using New York as an example on 13th Avenue it would be you know friday afternoon and a 14th Avenue they would be initial showed us if the tale I ran through borrow partner which would be of interest because you could keep shops two days or you could you know if you're busy with work you could spend shine you can spend Friday on 13th Avenue and then you know my lips and time go to Ford to Gavin you and now it's there Michelle should is here on our shop is and then you go back to work you know they're so that you can't have that there's an island suppose goes to land so you know when it goes to land the classic gray which means hugs it correctly the whole if you don't have the coast and the whole land is going to follow the the west so Australia for example follows the western part estrada there's an island in the Philippines called San Pedro island which is in the eastern visayas area and that island actually if you look you'll see that it has an issues Dateline mrs. it maybe by 50 60 feet which means that according to according to that that island is a Suffolk shabbos and cause a quintal constitutes an island so it's really you know it's ready to click on of communal whether that line now has your Navy feet makes a difference if it's a rabbit correct please the land or not actually come to think of it though maybe not femina now because it's other routes on the left side so I'll never give in around anything well it's either to the east of it no no I'm not my it may be on the west of it anyway so it hasn't ish might love you prompts I may be incorrect on that but we got another Island that's the case where the hundred eighty feet could make those I've give me this if you say graver they're not but it's not practically a case I I think I'm incorrectly and that's a scratch that from the record not take it more right it's going to be on the west side so contrast which is going to be hard will make enough movement I need a line on the other side okay okay fair enough okay I just want to reiterate we're here with rabid dog whatever in stark your offices our webinars are held the last Wednesday of every month and and if you want to join us or get the emails about what the webinars about send us an email to info @ star desh ke org also if you have questions about katras about anything else that we can help you with you can email it there a course at 410 44 4 110 just a point of reference next next month and July we'll be off for our summer summer break and continue God willing at the end of august um okay remember no sin came up his second this extra second from hot Java perspective Jewish outlook that the Gomorrah says the h co khone laga be shot office that a person can gain on hop in one second shower literally means in our bed over there it means 11 second person can do something in one second that he can what can you say in one second one second you say I'm sorry you know that takes a second you can do a lot of the same I think or since I have to too much cuz i'm here with the second one is first of all you see that by by bilham coming alone Russia is a parraga not actually a wrecker it is about seven or eight sheets as to how long a ring it is if he knew he knew the second when I shine was actually like a lot of days judging all the decimals that give a ragout all she does have an eight minute somehow it's point that I know the numbers in front of you but so I didn't keep them to Chris class all times to say as highly conserved short time I says that he started it started at CC you see me the peroneus rights artists can make problems in such a short time imagine how much you could do to do good at the time oh he could have Santos if it doesn't want to answer they could have said Colleen destroy the like right right destroy then more you could have started in that count exactly right daughter huh Chicago wish I say over sometimes enjoy and Russia's is about a second as follows you know it would be clients were mad acting in a lotta river in the dock taken in exactly when and there's a six-month furlough section Krishna and talk about time now and you really you know the dicta by is very important if a person is lacks in that same you know what's them as I miss it by five minutes or ten minutes or a few seconds like why is that promise I likely the following Marshall imagine you have a Super Bowl being played and your you know your team is playing and there's one second on the clock and you're at the your team is on the scores on scene 3129 and you're on the opposing teams you know ten you're online you know they call timeout clock stops with one second left and that all they need to do is bring out their field goal crew and kick a field goal in one second remaining and they win the super bowl and the referees come and say you know what a player 8 59 minutes 59 seconds what he dragged the cover is tired everyone's gone it's only a second anyway forget the second right it would be riots let me ride with you would go to the Supreme Court you know it would be it would be huge because it's actually there's a lot of money on the line there's a lot of pride on the line this discover there's so many things on the line that's all hanging on that one second that could be enough convener that any sport any sports fan will appreciate the huge difference between this team or that team winning its millions of dollars and ripple effect of what goes on so no referee whatever do such a thing so we'll handle delle of alpha on river ice right we're giving the opportunity to mitzvahs which are worth more than Super Bowl trophies and worth more than all that you know exponentially can even be a shire what it was worth so the every second does count em absolutely okay um and and and the leap second gave us an opportunity to talk about all the story itself itself it's maybe that's why they created a little take notes because i read somewhere exist no second i read that is even the dispute among the experts whether or not we need these leap seconds the institute of them in 1977 and then it's not clear not everybody's in agreement they want to solve them they don't need it were on the only seconds right so maybe we'll today it's the whole whole purpose of it maybe was the way we could have you know Tory webinar about it i once called government agency in Colorado I was working on as well so good and I want some information I stumble across this this Bureau and I called a lot but I asked the birth to something you know happy summer I remember exactly but I do a general time so the person said I only work on seconds he told me there was this whole job because it seems the press your professor of a second I don't think I mean it's just saying this right right right so father has been hours yesterday just alright sunset I'm only other tomorrow aster of the seconds uh-huh so I couldn't talk like you do know it is i found that fascinating i say that's interesting okay so um maybe we'll say maybe you'll say a few words about about the general impact of a stronger jewish calendar available would but so we know you know a lot of it we know it relates the tides it's madame x admirer of the chakras midsummer all relate to it the jewish calendar of course it relates to it and so on what what i wanted to focus on maybe is the impact of the homicidal of the nations of the world and their changes and how it impacts on our haha knows for example one example be savings time the same time is is of they add extra they don't and our they modify the clock of a throw as a clock ahead in the summer it's saving because you're basically shifting an hour of daylight from the early morning when most people are asleep to the evening where people could use it more so if Baltimore instead the Sun rising today for 40 and setting it the approximately seven forty it rises at five forty insensate a 40 and therefore the hour between 442 540 of sunlight were where most people were asleep is not transferred to the evening where most people are going to utilize that enough to turn on the lights on and so that's that's the lungs behind it but I knew impact on clients well the shabbos is an hour later what's a shabbos is an hour later people travel what's a shabbos means it's your anything an hour later on the clock we work we are we work by the clock it also you know Sun rises in the wintertime or the fall come difficult with Davenant because we were late because the right lane another October early November it's extremely late so people have child's with a diamond so early well still dark I want to mention that we did have actually we had a weapon are you that you spoke it's a it should be on our archives so if you want to look at Vimeo Starrcade kosher you'll see type in daylight savings time you'll see we ever expounds on at length I was other thing is the change was 1582 the calendar was changed in 10 days were taken out of the calendar and now every 100 years 3x three out of every hundred years 1700 1800 1900 2,100 2,200 there's a leap day that's trapped out and that has that has practical ramifications on talabot are and it also interesting enough really on our whole young type in because we're always keeping the Jewish calendar and sync with the secular calendar so like you know people like to have the summer schools typically start around Labor Day but yet in an early year that becomes difficult because we're spending kids go to school for Hashanah 1964 Arizona was Labor Day 1994 it was it was you know also the day the labor day and the next day was ever shot and so and become difficult had not been for the calendar change in 1582 rosh hashanah would commonly fall out in august that was a common with who definitely had an end of August it would end of august and you just think about it the Hebrew calendar would be 13 days earlier than it is which means on on just mentally that would be instead of Shoshanna beginning sometime between September 15 October fifth roughly it would begin you know august twenty-third September 23rd roughly we see a manager Hashanah being you know august twenty-third 25th so that change helped that actually helped that actually close enough I can't could be we would work differently it could be cool Oh be different school right we'll remember the season the eggs are puncture the seasons and but who knows who knows what happened but you know that's not it did have an effect I want to mention remember that that our sons are in the same class in school in the US reagan is graduation 500 songs Sally chapter graduation so I mention that that my son says that your son picked up this event you have four fours manan and my son says if you ask if you ask him if yes Molly like when is poor going to be in you know in four years I want to know what day every week is going to be said he'll think a few minutes or a few seconds and then and then I'll come up with it's gonna it's a thursday whatever is gonna give us what to talk about a little short right like so i said that you know it's really it's a wonderful thing with let's take some of these questions but and then we'll finish up ever ever okay there is a specific question manoj is asking about tantowel mother and I believe that when I should email that question to us and I think I've ever he's going to get back to separately on that Moshe says flying today from New York City to Israel be in Moscow you only get this year and then innate succumb meaning it is very little time didn't mean is that there's no there's no safe right yeah the promise when you fly this you find something you have admired what's happening there is that see if the planes would fly at the latitude if you know from New York two artists r all at the 40 degree latitude that New York is absolutely one degrees and then it would dip down then this problem what happened because the Sun go down a little earlier than New York because you've flown East the problem is in the summer is that the planes fly north because it's actually quicker to go with the called polar route of the Arctic route to fly very very far north over Iceland and so on even want to map on a flat map looks like going out of the way because it going up but the Great Circle Route Janssen comes out that comes out much shorter just the way to conceptualize it is that that the number of degrees latitude if you're going longitude from one to another actually the closer you get to the equator the more miles it is as if you go from 75 degrees to 76 degrees on a straight line at your latitude when you're at equator it's many more miles than when you go when you up and because I the candidate orbit room there right exactly if you look at it you'll see those latitudes seem to get closer lab to that I miles they are so anyway that's the great circle route so that the issue is because you going so far north you're you're you're in North as we know the further north you go the less less dark there is so that's really the issue my review you're lucky getting a sunset um according to least to the calculations you're looking at maybe it's a wonderful website high tables calm which will give you this you should not matter about the skia even though you if you normally downloading it's dark you know gram that opportunity if high tables told you the sun's going to go down sometime look out the window and if it's a little dark diamond and even if it's you know almost dark or or its it basically shakya ish you're at least a plug of inside you have the ability that my roof and then people have to wind on what it's about a dark as you think it's going to get let's say we should not gonna let that's you want to stop my remember remember you mentioned before the International Date Line I have one question for you when how many times do you cross that line fan scared it's a believer to 97 years believe it or not I was like to read the real date with addiction see the real the secular international date line lies a pc right I've never flown never been to Australia or flawed there it's a famous story of the hill to working on right there I was starting in yeshiva your day and there's a part of the body of the animal called the court come on and they got hold of it they said on this day and there's all the curcumin right that finally so what they are the only David look at daylight I did cross the recently for the first time I got to cross at least one day line which is the cash t how long how long am I what kind to one sheet one general opinion of whiskey and those who hold like him and that is a lie that's at the opposite side of you shall I am which is 12 hours east honey I degree hundred 180 degrees release down line is between California and Hawaii so I actually flew over that line going to Hawaii to do an initial inspection of the two facilities Dean Foods which is now coming on to the many to be to start start d products for their dairy products and power products eventually want to start k on then I want to know if they if they ask you to go so that you could go over a Dateline well it please also died about besides Hawaii in orbital why he hadn't had a list of states you know calculated but was interesting on the plane because I really wanted to know when are we crossing this line it had okay and there are issues you know which I was wasn't there was there in the middle of the week shabbos I appointed inshallah we put on tefillin again Lionel's you know no need to our opinions that hold you know maybe it should etc so that there are some trials to come up if they're certainly major shy as if of shops I was there on a tuesday and wednesday i was in a little the initial inspection there that i was in hilo which is uh to the east anyway on the plane I asked the flight attendant you know what's the what longitude oh yeah so I realized the pilot so the pilot said to her no one's ever asked that question for so turned out we were east of that of where we were then I thought you can bring your gps on a plane you and it will work yeah cool if you can work it because the satellites I know it's not communicating like back and forth I think it's legal haha ok I didn't think that anyways I asked again later next thing I figured were around there just another like it means that much to you look fancy water the pacific ocean by asked the you know we're the lab to too late looked at me strangely and i had to say well last I tend to just ask the pilot so they call the pilot leader right across the head see because the best online this day and age gather you don't watch with the a idea one they're carefully they think they know who loves it no who knows okay I was I looked it up oj religious reasons enough okay all right ever ever so so we want to thank
