Why does it get dark so late in Tibet? What is the reason?

The main reason why it gets dark late in Xinjiang is geographical location. The sun turns from west to east, so the east we mean will see the sunrise first. In China, a large area is located in the east, and the longitude is about 120, but Xinjiang is different. Xinjiang is located at 73 40' to 9618' east longitude. Our daily time in Beijing is in the East Eighth District, while Xinjiang is located in the East Sixth District, so this has caused a two-hour time difference.

There is a certain time difference between Tibet and the mainland. In spring and summer, it usually breaks at around 6 o'clock and gets dark at around 9: 30 in the evening. Generally, dawn breaks around 7: 30 in autumn and winter, and it gets dark around 8: 00.

First of all, from the perspective of latitude and longitude, the latitude of Xinjiang is higher than that of other parts of China. From March 2 1 day to June 22, the direct point of the sun will move to the equatorial line. At this time, the higher the latitude, the longer the day and the shorter the night. But Xinjiang has a higher latitude, so the sunshine time will be longer than other areas.

Tibet uses Beijing time the same as the whole country, and China uses Beijing time uniformly. But the time difference between Tibet and Beijing is obvious. According to the general calculation method, the east longitude of Lhasa is 9 1 degree, and that of Beijing is about 1 16 degree, with a difference of 25 degrees, so 4x25= 100, and the time difference between the two places is 100. In addition, the most accurate statement at present is that the time difference between Lhasa and Beijing is 1 hour 55 minutes and 34 seconds.

All of China (Chinese mainland, Hong Kong, Macao and Taiwan provinces) use Beijing Time (UTC+8), but in Xinjiang and Tibet, although the demarcation points of government agencies, enterprises and institutions and postal communication fees are all expressed in Beijing Time, they are two hours later than other provinces. For example, China Telecom's long-distance telephone discount time was delayed for two hours in Xinjiang and Tibet.
