Diurnal

Diurnal (/daɪˈɜːrnəl/; from Latin diurnus "of the day", from dies "day") is a term in chronobiology used to describe organisms that are active during the daytime and sleep at night. It is the opposite of nocturnal, which refers to organisms that are active during the night and sleep during the day.

Etymology

The term diurnal comes from the Latin word diurnus, meaning "of the day". This, in turn, is derived from dies, the Latin word for "day".
