What time does it get dark in Xinjiang 12 18?

I don't write geography or astronomy, but I know it's dark in Urumqi 18, about 6 o'clock.

The time of sunrise and sunset in the same dimension is mainly the same as longitude, and extreme days and nights will occur in high latitudes.

I have never been to Sanya. It's at low latitudes.

Check the latitude and longitude of the two places, check the law of the earth's revolution and rotation, and then check where the direct point of the sun is in 65438+February 18, and you should be able to analyze the sunset time difference between the two places.

Hehe, I don't know.
