The time difference between China and France: China is 7 hours ahead of France.

China calculates time based on the East 8th zone of the time zone where Beijing is located, while France calculates time based on the East 1st zone of the Paris time zone. The time zone difference is 7, that is, a difference of seven hours, so when Beijing time is 12 At 12:00, Paris is still 12-7=5:00. If the two places are in the same hemisphere, the dates will be the same.

Extended information

The world is divided into 24 time zones (12 time zones in the east and 12 in the west). It is stipulated that the United Kingdom (the former site of Greenwich Observatory) is the middle time zone (zero time zone), East 1-12 zones, and West 1-12 zones. Each time zone spans 15 degrees of longitude, and the time is exactly one hour. The final east and west districts 12 each span 7.5 degrees of longitude, bounded by 180 degrees east and west longitude. The time on the central meridian of each time zone is the time uniformly adopted in this time zone, which is called zone time. The time difference between two adjacent time zones is 1 hour.

For example, the time in East District 8 of China is always 1 hour ahead of the time in East District 7 of Thailand, and 1 hour behind the time of East District 9 of Japan. Therefore, people traveling abroad must adjust their watches at any time to be consistent with the local time. When walking westward, every time you pass a time zone, you must set your watch back one hour (for example, from 2 o'clock to 1 o'clock); when you go eastward, every time you pass a time zone, you must set your watch forward one hour (for example, from 1 o'clock to 1 o'clock). 2 o'clock). And it is stipulated that Britain (the former site of Greenwich Observatory) is the prime meridian, which is the zero degree longitude.
