Evening

Evening is a daily astronomic event of variable time period between daytime and night. Evening occurs between sunset and dusk (last light). There can be no precise definition in terms of clock time, but it is socially considered to start around 6 p.m. and to last until nighttime or bedtime. Social and family activities are often held during this time, such as supper or more formal social gatherings and entertainment, such as parties, in particular dance parties. The word is derived from the Old English ǣfnung, meaning "dusk falling, the time around sunset".
