<P> Evening is the period of time at the end of the day, usually from about 6pm to bedtime . It is a daily astronomic event of variable time period between daytime and night, and the period in which the daylight is decreasing, after the afternoon and before night . There is no exact time for when evening begins and ends (equally true with night). Although the term is subjective, evening is typically understood to begin shortly before sunset and during twilight (sunset and twilight vary throughout the year), lasting until night--typically astronomical sunset . There can be no precise definition in terms of clock time, but it is socially considered to start around 6 pm. and to last until nighttime or bedtime . </P> <P> The word is derived from the Old English ǣfnung, meaning "the coming of evening, sunset, time around sunset", which originated from' æfnian' meaning "become evening, grow toward evening". The Old English,' æfnian' originated from' æfen' (eve), which meant' the time between sunset and darkness', and was synonymous with even (Old English æfen) which meant the end of the day . The use of evening dates from the mid 15th century . </P>
