Time difference between Vancouver and Beijing

Beijing is the East Eighth District and Vancouver is the west eight District, with a difference of 16 time zones, that is, 16 hours.

The difference in local time between two areas is called time difference.

Local time: With the rotation of the earth, the sun rises in the east and sets in the west in a day. When the sun passes the highest point in the sky, the local time is 12. Therefore, different longitude lines have different local time. The same time used in the same time zone is the time zone (local time on the central meridian of this area), and the same time used around the world is universal time (local time on the meridian of 0 degrees).

I. Division of time zones

In order to overcome the time confusion, an international longitude conference (also known as the International Meridian Conference) held in Washington in 1884 stipulated that the world should be divided into 24 time zones (East 12 time zone and West 12 time zone). Britain (the former site of Greenwich Observatory) is defined as the central time zone (zero time zone), East 1- 12 and West 1- 12.

Each time zone spans longitude 15 degrees and the time is exactly 1 hour. The last east-west zone 12 spans longitude 7.5 degrees respectively, and is bounded by east-west longitude 180 degrees. The time on the central meridian of each time zone is the time uniformly adopted in this time zone, which is called time zone. The time difference between two adjacent time zones is 1 hour.

For example, the time of China East Zone 8 is always 1 hour earlier than Thailand East Zone 7 and 1 hour later than Japanese East Zone 9. Therefore, people who travel abroad must adjust their watches at any time to keep up with local time.

Set your watch back to 1 hour every time you go westbound (for example, from 2 o'clock to 1). Set your watch forward 1 hour every time you go east (for example, from 1 to 2 o'clock). It is also stipulated that Britain (the former site of Greenwich Observatory) is the prime meridian, that is, the zero meridian.

Second, the calculation method of time difference

Subtracting the standard time of two time zones (real-time area code) is the 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.
