![]() ![]() But for now, you'll have to stare at the time zones' contortions. Irregularities like those are part of the reason some make the argument we should move to a single Earth time instead of many time zones. Though this has occasionally caused difficulties in Western provinces, the country officially lives on "Beijing Time."įor comparison, here's a time zone map with the countries shown:Ī map of time zones (with land). China spans what would normally be five hours of solar time - but you can see its outline on the map because it only uses one time zone.That has, however, caused some states to protest and follow their own time zones. India is visible because despite its size, the entire nation has adopted Indian Standard Time since gaining independence from Britain.Moving to the center, you can see the outline of Argentina, because it uses the same time zone as eastern Brazil (unlike Bolivia and Paraguay, which sit above Argentina and use the time zone used in western Brazil).Politically, it makes sense that Alaska time would be the same everywhere, but in practice it can be confusing, since the solar time can vary two to three hours from the clock time. That huge jag in the top left corner is the adjustment for Alaska, which is one single time zone.Still, that idea has led to some quirks that are visible in the map above: States in the eastern time zone include Main, Vermont, New York, New Jersey, and Ohio. During EDT or daylight savings, the eastern time zone has an offset of -4 hours for UTC-GMT. By the 1900s, the idea was widely accepted and practiced. Eastern time zone is also referred to as EST for Eastern Standard Time and EDT for Eastern Daylight Time. The idea for a worldwide time-zone system gained currency at the International Meridian Conference in 1884. Time zones were meant to solve the problem of different solar times around the world (solar times are what time it feels like based on the sun's position in the sky). It highlights just how unusual these artificial boundaries can be: Branden Rishel created this map showing only the world's time zones - without any of the land underneath.
