day night

Sun then moon

Day night describes a continuous period spanning both daylight and darkness hours, or the full cycle of a single rotation.

Sports events use it for doubleheaders where one game is played in afternoon and another after dark: We've got tickets to the day night at Fenway.

The phrase emphasizes duration or completeness: She worked day night to finish the project.
