For example, this United States time zone map shows the six designated time zones including Eastern, Central, Mountain, Pacific, Alaska, and Hawaii-Aleutian time zones. Time zones can have names to help easily identify them. Other examples include Afghanistan, Venezuela, and Australia with unusual time zones. Time zone abbreviations list GMT Greenwich Mean Time, Sat 12:00 AM GST Gulf Standard Time, Sat 4:00 AM GST South Georgia Time, Fri 10:00 PM GYT. But the province mostly observes Atlantic Standard Time (AST). Also, there can be “irregular square” time zones similar to islands.įor example, the province of Newfoundland and Labrador contains its own time zone with the same name that is UTC -3:30. Instead, they are jagged and adapt to the political boundaries of countries. This system has been adopted internationally by setting the total time difference around the world as 24 hours. There are 24 regions (Time Zones) around the world with a time difference of one hour.
No time zone in the world runs a perfect north-south line. (As of August 2020) Time zones and time differences There are time differences around the world based on Coordinated Universal Time (UTC). Whereas when you go from the west across the International Date Line, you turn your calendar ahead one day. When you cross the International Date Line moving toward the east, you turn your calendar back one day. The center of the time zone roughly follows 180° longitude without crossing any landmass. The International Date Line is a north-south line in the Pacific Ocean where you turn your calendar back or ahead one day. Whereas it would be 8 am at 60°W longitude International Date Line For example, it would be 4 pm at 60☎ longitude when it’s noon at the Prime Meridian. You can find any time by counting how many degrees longitude it is away from Greenwich. World Time Zones by Country List, UTC (GMT) Standard, Worldwide List Time Zone names, codes and abbreviations for Standard Time and Daylight Saving Time (DST) around the world. But when you head toward the left, you lose an hour (slow time). Time and World Time Zones and time map with current time around the World and countries operating Daylight Savings Time sunclock map shows what part of the.
In other words, for every time zone that you move towards the right, you add one hour.
When you move to the right, you gain time (fast time). Then, the next time to the east spans 7.5☎ to 22.5☎. This means the Prime Meridian time zone spans from 7.5°W to 7.5☎. The Prime Meridian ( Greenwich Meridian) defines the center of the first time zone in the world. Because the Earth rotates 360° every 24 hours, each time zone is 15° longitude apart from the other. We have 24 different time zones in the world.
