A diurnal animal (dī-ŭr'nəl) is an animal that is active during the daytime and sleeps during the night. Animals that are not diurnal are either nocturnal (active at night) or crepuscular (active primarily during twilight). Many animal species are diurnal, including many mammals and birds. The human species is diurnal but has adapted to nocturnal activity also with the aid of artificial lighting.

A nocturnal animal is one that sleeps during the day and is active at night - the opposite of the typical human schedule (diurnal). The intermediate crepuscular schedule (twilight activity) is also common. Some species are active both during the day and night.
