Weather forecast: Will the sunset start or end?

1. The sunset time in the weather forecast usually refers to the time when the sunset starts, not the time when the sunset ends. Specifically, when the sun falls below the horizon, the light will gradually weaken until it finally disappears completely. Usually this process takes several minutes to ten minutes, so the sunset time given in the weather forecast is a rough estimate.

2. The sunset time in weather forecast refers to the time of sunrise and sunset, which is usually expressed as hours, minutes and seconds in 24-hour format. Among them, the sunset time usually refers to the moment when the sun disappears from the horizon, that is, the moment when the center of the sun sinks to an angle of zero degrees with the horizon.
