by day

He sleeps by day and works by night.

Il dort le jour et travaille la nuit.

We work by day, and rest by night.

Nous travaillons le jour et nous nous reposons la nuit.

If by day six, we don't have a solution, you dump the station and fly back home.

Si au sixième jour, nous n’avons pas de solution, vous abandonnez la station et rentrez chez vous en avion.

— Salyut-7 (2017)

"By night one way, by day another."

La nuit d’une façon, le jour d’une autre.

— Shrek (2001)

Travel only by day.

Ne voyagez que de jour.

— The Lord of the Rings: The Fellowship of the Ring (2001)

Fear not the terror by night, nor the arrow that flies by day.

Ne craignez ni la terreur de la nuit, ni la flèche qui vole le jour.

— City of God (2002)
