What's the time difference between the United States and China?

The United States implements daylight saving time, and Beijing time is just 12 hours earlier than American Eastern Time (E.T.). Non-daylight saving time, Beijing time is earlier than US Eastern Time 13 hours. Therefore, the time difference between China and America can be divided into standard time difference between China and America and daylight saving time difference between China and America. Because there is only one time standard in China, which is Beijing time.

The United States spans the west coast from east coast to west coast, and there are six time zones from the west fifth district to the west tenth district. China adopts the East Eighth Zone Time, so the time difference between Xia Dong and other parts of the United States is different.

Time difference calculation between China and America:

Calculation method of time difference: the difference between the standard time (real-time area code) of two time zones is time difference, and the time zone with larger value is earlier. For example, China is the eighth eastern district (+8) and the eastern part of the United States is the fifth western district (-5). Time difference between the two places 13 hours, Beijing is earlier than new york 13 hours. If it is the period of daylight saving time in the United States, the difference is 12 hours.

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). For example, the United States implements DST from April to September every year, one hour in advance.
