When does it get dark in Tibet? What is the difference between Tibet and the mainland? Is winter the same as summer?

According to the calculation of Purple Mountain Observatory in Lhasa, China Academy of Sciences

Sunrise time: 65438+1October 1 8: 5 1 sunset time: 19: 07.

Sunrise time: March 8:22 1 sunset time: 19: 55.

Sunrise time: May 1 7: 14 Sunset time: 20: 33.

Sunrise time: July 1 6:59 and sunset time: 2 1: 0 1.

Sunrise time: September 1 7: 4 1 sunset time: 20: 18.

Sunrise time: 165438+ 10/8: 09, sunset time: 19: 09.

For comparison, the data of Beijing are listed separately:

Sunrise time: 65438+1October 1 7: 36? Sunset time: 16: 59

Sunrise time: March 6:38 1? Sunset time: 18: 06

Sunrise time: May 1 5: 15? Sunset time: 19: 09

Sunrise time: July 1 day at 4: 50? Sunset time: 19: 47

Sunrise time: September 5:42 1? Sunset time: 18: 46

Sunrise time: 165438+ 10/0/6: 44? Sunset: 17: 13

So the mainland is about an hour and a half ahead of Tibet.

1. At sunrise, sunlight is Rayleigh scattered by dust in the earth's atmosphere, so the sky will be filled with smog, but the smog at sunrise is more elegant than at sunset, because there is less dust in the atmosphere at sunrise than at sunset. The time of sunrise will change with the season and the latitude of different places.

2. The time of sunset will change with the seasons and latitudes in different places.
