In the old days, when there were no clocks, people used to use the sun as the standard to determine daily time. Later, when life became more modern, people could easily calculate the time zones around the world. In each different country, there will be different hours.

The earth has 24 meridians dividing the earth's surface into 24 equal parts. Each meridian corresponds to 1 time zone. Helps us easily calculate the time difference between countries. However, the above division is only a general basis; Specific time zones are built based on local agreements, which have an important element of national territorial unification. Therefore, on the world map, many exceptions can be seen, and the time difference between some time zones can be less than 1 hour.

Below is a table of time zones of countries arranged in alphabetical order for readers to easily follow.
