Sunrise and sunset schedule in 2023

Sunrise and sunset times are different in different areas.

If you want to know the specific time of sunrise and sunset in a certain area on this day, you can turn on the weather forecast that comes with your mobile phone, which has the accurate time.

Sunrise refers to the sun rising from the horizon or seeing the sun for the first time. Sunset means that the sun disappears from the horizon. So how to calculate the specific time of sunrise and sunset?

Sunrise time = 12 day length, sunset time = 12+ day length.

On the contrary, the length of day and night can be calculated according to the sunrise and sunset time of a certain day in a certain place. The method is as follows:

The day length of a place = sunset time-sunrise time = (12 noon-sunrise time) ×2= (sunset time-12 noon) ×2, and the night length of a place = (24 midnight-sunset time) ×2= (sunrise time -0 midnight) ×2.

Sunrise and sunset time: sunrise before 6 o'clock in summer and sunset after 18 o'clock; In winter, the sun rises after 6 o'clock and sets before 18 o'clock. Spring and autumn equinox, sunrise at 6 o'clock, sunset 18 o'clock.

Is the sunset mainly related to longitude or latitude?

Mainly related to latitude. When the angle between the sun's rays and the ground level is large, it will shine at the higher latitudes and even the polar regions on the Tropic of Cancer, so the sunset time will be longer; If the earth is on the side of the Tropic of Cancer, close to the equator, and the latitude is low, my sunset time will be shorter.
