Time zones are based on the fact that the Earth moves 15 degrees longitude each hour. Since there are 24 hours in a day there are 24 standard time zones on the globe. (24 hours x 15º = 360º)
Time zones are counted from the Prime Meridian (0º longitude). Each time zone is counted at 15 º intervals and extends 7½º either side of a central meridian. For example, Sydney, Australia lies in the 150ºE central meridian, and the time zone includes all locations between 142½ºE and 157½ºE.

The only green witch I know is the one in the wizard of oz

@@TheRoboRyan No he was Telling a joke. Greenwich means time
I can recommend Greenwich (pronounced 'GREN-itch') as a great place to visit. Lots to see for everyone: mum, dad, the kids and the grandparents. For example: Royal Observatory, Cutty Sark, National Maritime Museum, Queen's House, Greenwich Park, Greenwich Market, Old Royal Naval College, boat trips, cable car (over the Thames), the O2, Greenwich foot tunnel (under the Thames), the Docklands Light Railway, pubs, cafes, restaurants, tea shops and sausages.
ALL pronunciations are valid! No "right" and "wrong" way please! Time to come together as a human family 🌟🌤️
for a 7years old video.this is as good a video as they can come... thank you
i was forced to watch
It's so hilarious to see on Google Maps that some of Kiribati is at the same longitude line with Hawaii but there is a 24 hour difference between the two. I'm looking at this now and it's literally 10:48PM January 1st, 2021 in Napari Kiribati, but it's only 10:48PM December 31st, 2020 in Honolulu Hawaii!
This video is really helpful. I had some doubts related to the IDL but it all got cleared when you mentioned that this line is drawn exactly opposite to the prime meridian. 👍
Trying to understand but i am on my meds. Is there any nice picture explained? Cant find it at all
Thank you for this clear explanation.
Best Thing I loved about this video is that its available in All Major Subtitle Languages 😍
Please highlight this comment.
yesss
Thank you! This was super helpful
what a great video.. was so confused until I watched this.. great job man
Thank you this video is super helpful.
When you cross the international dateline in an easterly direction you subtract a day, but when you cross a midnight zone in the same direction you add a day. You add a day if crossing in a westerly direction and and subtract a midnight zone. Sometimes these additions and subtractions will cancel each other out and two positions will be on the same day.

One of the most satisfying VIDEO EVER I HAVE SEEN
Great work man. Very CLEAR explanation. Thank you.
Thank you this was very helpful and informative 👍👍
realy
Yea thanks buddy
Vừa vào đã nổi cả da gà 藍giọng a Phúc hayyy quá, mong sẽ tiếp tục cover ạ ❤️
Thank you so much
All very entertaining but what time is it on the Ross ice shelf?
I read that from 10:00 AM to 12:00 PM UTC it is 3 different days for the earth. For example at 11:00 PM on December 31st in baker island and Howland island in the central area of the pacific ocean it is january 1st for the majority of the world and 1:00 AM on january 2nd for Kiribati's line islands. Which is 26 hours later then the local time of baker island and Howland island.
Thanks for this video
I need a much simpler version of this and actually explaining.
This video is so understandable 👍👌
You could just Google it to find out the time there and the International date line used to be on Land when Alaska was apart of the Russian Empire, It only moved from when Alaska became apart of the United States
cool accent and the video also helped a lot
Great video! Thank you!
Thank you; that was very informative.
Good video!
good stuff
Thank u very much 🌻👍🏼
Very informative and awesome, loved the beginning bit too about the towns being confusing. I’m sure they were - how could people ever commute far distances to work if they had to switch time zones during the commute!?! They’d need 2 watches! So strange:)
P.S. very handsome and pleasant accent, too!!! ;P
nice video
what a sick accent
This is lesson
That is discrimination, my friend.
Agreed
I dont get it
People, "Sick" is a complement in this context.
On the opposite side of the world to the Prime Meridian is the Antipodal Meridian (180 degrees longitude) The International Date Line also runs down this line, except it bends around some countries to keep that country i the same time zone. Hawaii and Australia are on different sides of that date line and are therefore on different days. The sun rises in the east and Australia will see the sun before Hawaii. By the time the sun rises in Hawaii, it will be the next day in Australia.
Am I the only one that finds it completely ridiculous that there is a 21 hour time difference from Australia to Hawaii? Maybe it's time we re-evaluate these things.
mate there is only a 3 hour difference
@@goatmaneagle no 21 hour difference. Hawaii is 3 hours behind California instead.
Hawaii is 3 hours behind of California, when California uses daylight time from March to November. From November to March California is 2 hours ahead of Hawaii.
Thanks
It was helpful
thanks
What is UTC, EST, ET and many more? And how do you find where it is and calculate what time is there?
I work in IT and we are all over the world, it gets a little confusing.
Very helpful
I feel dumb. I don’t understand a thing
Same here T-T
😂
thanks!
Brilliant... Made easy... Is there a place where night leaves and day adverts simultaneously?? It's confusing.. Nevertheless it's amazing how u teach..
Nice video
Have a nice day
I love your voice!
Does anyone know whats the timezone rn for turkey?
good
Thanks
This taught me more than my geography teacher
Are the time zones meant to line up so that the areas within the time zones have the same approximate sunrise/sunset times? In other words, are they designed to line up with daylight?
Same, my thought was for it to be around 12:00 when the sun is directly over head,no?
nice
I live in Buenos Aires, and I also saw that it was in UTC -4 which is why I missed the red moon on Apr. 14, 2014. They ridiculously have the country in UTC -3 even though it doesn´t belong there, so you might want to make a corrective comment in your video.
This is correct lesson
That means Buenos Aires local time is 1 hour later than the original time zones
Your clocks shows a later time
So if a person sitting at exact data line steps towards east he gains 1 day extra n if he steps to west of data line lose 1 day(24 hrs).? M i ryt?
THIS ! SOMEONE PLEASE ANSWER THIS !
i did not get single word that came out of his mouth lmfao
Lmao me too
What if you lived west of Sydney (142°30’E) you could step one side and be in one time zone and then step the other side and be in a different time zone
All of Sydney has the same time zone every day of the year. If you were in New South Wales, the state Sydney is in at 11:59pm on New Years eve, celebrated the new year and then step into Queensland before the next hour you could celebrate a second new year in the same night.
Thanks for this video, it was very useful!
Am i the only dumb one that doesn't understand anything?
No I also here
Same
Same
your not the only one
me too
Cool
Nicely explained, Thanks.
Well-done sir ..... really gud .
no
With today's smart technology we can easily go back to old fashion timekeeping. Computers will easily calculate all differences in time.
Fyi, Greenwich is pronounced "Gren-itch". No idea why.
Why is Worcester pronounced Wuster?
Why is Leicester pronounced Lester?
W is silent
If there are 32 lines separating 33 segments, there has to be 33 hours in a day at the equator no matter what, or else time falls behind it is contradictory
damnnn I understand now!!! thank youuuuu
Argentina (and it's capital Buenos Aires) is at UTC -3:00 all year by law even if the entire country is on the theorical UTC -4:00; except the province of San Luis which in the past had time zone changes in DST as most of the country is in standard time, the last time was during the 2000-2009 period were by law the applied or not.
Just to clarify, I'm not from Argetina nor live as a resident there.
Any video explaining all the terms? AST, etc? UTC/GMT the correlations etc?
Did you find any?
@@yashankgoswami1119 Not yet.
Thnx
THANKYOU!!!! LOL I'm trying to teach 2 friends WHY it's 5 am in Canada when it's noon in Britain!!! LOL
When your travelling east it’s always later time
Example
If you travel New York to London
You will have a later destination
London to New York
You will have an earlier destination
I give you ex.Manaus city In Brazil is located on 60degree longitude what would be the local time at manaus when it is 12 noon at green wich
We watched this in Geography class ;)
I'm sure you guys didn't understand shit.
useful
My time zone is the best time zone, MOUNTAIN TIME OR BUST!
thanks it has really helped
Daylight savings goes for too long, it is still dark at 7 in the morning , on nsw/qld border. (And qld doesnt do dst, just to confuse things, new years is celebtated x2, at tweed heads/coolangatta).
that's how fast the night changes 😀
You kept saying Greenwich wrong.
there is only one time. and that is now
🤯
I can travel through time?
That last part fucked me up lol
welcome 2020
Any time difference neitherland from india
International date line, my next research to learn!
Wow
What a stick access
Wait .. you can see the fireworks 2 times jest go in a country time zone for example +1 and then travel to a country with time zone 0 and you can see again fireworks for new year
u Australian mate?
YEAH KIWI!!!! we have the best accent!
Yes, cool accent
Greg Simonson I like what you said
They just casually skipped a day...
You saying that reminded me that everything is made up
dates and the numbers on the clock, is all just an invention. (It's a wonderful way to stay organized though)
There's even a different time zone here on Earth for fast moving object like airplanes .00001 nanosecond slower as well as different time zone for satellites ;)
@Eu Singur do your research.
Question : 11 pm sunday on 165 E of the meridian what will be time on 165 W?
Confused 165+165=330 divide by 15=22 timezones or 22 hr so it should be 1 am Saturday.but Answer is 11 pm on sat,
can anyone explains me why?
is it because from meridian to +1 and -1 =2
This is so confusing if only there was a class about this
I need to watch for school
Same :/
awesome explanation...
[5-3 21:41] Mahamuda Manjur Runa: czcams.com/video/Fe08ZD7iKJY/video.html
[5-3 21:45] Mahamuda Manjur Runa: czcams.com/video/ZjZneawVueY/video.html
so if i crossed between russia and alaska, at some point i will time travel 23 hours in the past
I’m just a mile away from prime meridian
anyone here because their teacher is making them watch this?
specifically mrs. janssen?
green eggs and sam Nope
Does India and Vietnam share the same time zone
Nope. India is an hour and a half earlier than Vietnam. If it's 12:00am (0:00) in Vietnam then it would be 10:30pm (22:30) in India. Not from either one of those places, just clarifying.
But where I *am* from, India is 10 1/2 hours later than us, while Vietnam is 12 hours later than us.
So basically it was an agreement
An agreement that 9am isn't in the middle of the night, but also that the minutes of a clock should be synced up instead of having 1 city saying it's 11:04 and another saying 11:18 at the exact same moment.
