Timezone of Worlds All Countries

Time zones are regions of the Earth that have a uniform standard time for legal, commercial, and social purposes. They are convenient for scheduling events and communication, as people in the same time zone can coordinate with each other without needing to account for variations in local time.

The world is divided into 24 time zones, each one covering 15 degrees of longitude. The time zones are generally centered on the Prime Meridian, which is 0 degrees longitude, and the International Date Line, which is 180 degrees longitude. The time zones are designated by the letter "Z" followed by a number, with "Z" standing for "Zulu" time, which is another term for Coordinated Universal Time (UTC).

UTC is the standard time reference for the entire world. It is the time at the Prime Meridian, and it does not change with the seasons or daylight saving time. UTC is used as the basis for calculating local time in all time zones.

The time zone that is one hour ahead of UTC is designated as "UTC+1", two hours ahead is "UTC+2", and so on. The time zone that is one hour behind UTC is designated as "UTC-1", two hours behind is "UTC-2", and so on.

Here is a list of some of the major time zones and the countries or regions that are located in them:

Time zones are regions on Earth that have a uniform standard time for legal, commercial, and social purposes. They are convenient for areas in close proximity to each other, such as countries, and are necessary for coordinating activities such as transportation and communication.

In total, there are 24 time zones in the world, each one covering 15 degrees of longitude. The world is divided into the Eastern Hemisphere and the Western Hemisphere, and each hemisphere is further divided into 12 time zones.

The International Date Line, located at 180 degrees longitude, separates the Eastern Hemisphere from the Western Hemisphere and is used to determine the date in different parts of the world.

In the Eastern Hemisphere, the time zones start at UTC+14 and decrease by one hour for each 15 degrees of longitude. The first time zone, UTC+14, is located in the uninhabited Line Islands in the Pacific Ocean and is the furthest east. The last time zone, UTC-11, is located in the Midway Islands in the Pacific Ocean and is the furthest west.

In the Western Hemisphere, the time zones start at UTC-12 and increase by one hour for each 15 degrees of longitude. The first time zone, UTC-12, is located on Baker Island and Howland Island in the Pacific Ocean and is the furthest west. The last time zone, UTC+12, is located in the Kamchatka Peninsula in Russia and is the furthest east.

The time zone that includes the Prime Meridian (0 degrees longitude) is UTC+0, also known as Greenwich Mean Time (GMT). This time zone is used as a reference for all other time zones in the world.
