On the contrary, the day length and night length can be calculated based on the sunrise and sunset times of a certain place on a certain day. The method is:

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