Understanding Time Zones

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.

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.

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. 👍

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.

[knowledgeringsstalkers]

One of the most satisfying VIDEO EVER I HAVE SEEN

[vietl]

What is UTC, EST, ET and many more? And how do you find where it is and calculate what time is there?

[Choronzon]

I work in IT and we are all over the world, it gets a little confusing.

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.

Brilliant... Made easy... Is there a place where night leaves and day adverts simultaneously?? It's confusing.. Nevertheless it's amazing how u teach..

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

[hehehehhohohoho]

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
