<P> 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". </P>
