>This article describes the time of day. For the work by Elie Wiesel, see Night (book). For the Norse goddess see Nótt. Night is the time when a location is facing away from the Sun, and thus dark. On Earth, it is night on just under half the planet at any time. When it is night on one side of the planet, it is day on the other side. Because of the rotation of Earth about its axis, it is alternately day and night, which together form a 24-hour day. The Earth's tilt also means that the nights are shorter in the seasons of summer and longer in winter. See more at Wikipedia.org...
