In the times before world timezones, people would often find it nearly impossible to schedule meetings at a long distance due to the difficulty in coming to an agreement on what time it was. Though this does not sound like a major problem, it does make many things difficult to describe, such as the time of day. If we didn’t have world timezones, scheduling trains would be nearly impossible, planning meetings in different countries would quickly prove problematic, and similar issues would arise daily.ĭaylight doesn’t hit the world uniformly, which means that if there was a single standard time worldwide, you would have a completely different impression of what 10:00 AM would look like. Using local or solar time makes it nearly impossible for modern society to work. World timezones were created in order to create a certain amount of uniformity in how people describe their time of day in different parts of the world. World timezones are actually a relatively new part of the way that the civilized world works. Map of timezones A Quick Guide To World Time zones Despite these variations, the time zone map provides a useful representation of the global time system. As a result, some time zones may be quite large, while others may be quite small. Time zone boundaries can be somewhat arbitrary, as they are often based on political and economic considerations rather than purely geographic ones. Time zones to the west of the Prime Meridian are ahead of Coordinated Universal Time (UTC), while time zones to the east are behind UTC. The time zones are centered on the Prime Meridian, which is 0 degrees longitude, and the International Date Line, which is 180 degrees longitude. The time zone map is divided into 24 time zones, each of which is 15 degrees wide. The time zone map can be useful for understanding the time differences between different parts of the world and for planning international communication and travel. Each time zone is represented by a different color on the map, and the time in each zone is displayed in the center of the zone. The time zone map is a map that shows the various time zones around the world. This is done to make better use of sunlight during the longer days of summer.

Many countries observe DST, which temporarily shifts the standard time in a region by one hour during certain parts of the year. There are 40 distinct time zones in the world, not including Daylight Saving Time ( DST) adjustments. Time zone abbreviations are typically three letters long and represent the common abbreviation for each time zone. Each time zone is represented by an abbreviation, such as EST for Eastern Standard Time or GMT for Greenwich Mean Time.

The index of time zones is a list of time zones sorted alphabetically by region.
