Whereas when you go from the west across the International Date Line, you turn your calendar ahead one day. Take a look at the official world time zone map. As stated above, all nations have specific interests, so the time zone map is not linear as it should be in theory. As a result, local time always depends on what time zone youre in at a given moment. When you cross the International Date Line moving toward the east, you turn your calendar back one day. So, we all end up getting 24 standard time zones and 14 additional exceptions. 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.

The Prime Meridian ( Greenwich Meridian) defines the center of the first time zone in the world. There are currently 38 observed UTC offsets in the. A UTC offset is the difference in time between UTC time and a location's observed time. This page lists all countries of the world, plus major regions and cities, grouped by their current UTC offset. Because the Earth rotates 360° every 24 hours, each time zone is 15° longitude apart from the other. Time zones List of countries grouped by current UTC offset. We have 24 different time zones in the world.
