What time zone is Japan in?

Japan is in the East Ninth District. Japan and China are neighboring countries, separated by only one time zone. China is in the East Eighth District, and Japan is one hour ahead of China.

The standard time everywhere is Greenwich Mean Time plus (+) or minus (-) the time difference between hours and minutes in the time zone. Many countries also adopt daylight saving time (DST), and the United States implements DST from April to September every year, one hour earlier.

The calculation time should follow different time zones, with the same reduction and different increase, and the east plus the west minus. "Same" refers to the same time zone in the East or the same time zone in the West. When the two time zones are subtracted, the time difference between China and Japan is 9-8= 1.

Extended data:

There is no uniform conversion method for using time in different countries, which brings inconvenience to transportation and communication. In order to unify, all countries in the world have adopted the time difference system and followed this system, and their time calendars are based on this system.

24 time zones correspond to 24 hours of a day. That is, 24 hours back to the original point, and 24 time zones cover the whole world. Based on the principle of zero-time coordinate axis, the time difference can be calculated conveniently by addition and subtraction.
