Generally speaking, the evening consists of the hours from just before sunset to just after dusk or bedtime, or approximately 4 p.m. to 10 p.m. In general, “evening” refers to a period of time that falls between afternoon and night.
In the Midlands of England and the southern United States, “evening” is used to designate an even longer time of the day. In these regions of the world, “evening” begins at approximately 12 p.m. and ends just after the sun sets.
