'''Night''' is the portion of a twenty-four hour period when it is dark, as opposed to [[day]] when it is light. The darkness is caused by the [[earth]]'s rotation, turning one side of the earth away from the [[sun]] which provides the source of light.
According to the book of [[Genesis]], night was created at the end of the very first day. In other cultures, night has been personified as a [[goddess]], like the [[Greek]] [[Nyx]].
