la nuit
He sleeps by day and works by night.
Il dort le jour et travaille la nuit.
Traveling by night?
Vous voyagez de nuit ?
— The Visitors (1993)
We work by day, and rest by night.
Nous travaillons le jour et nous nous reposons la nuit.
What you can't get away with by light of the day, you try by night?
Ce que tu ne peux pas faire impunément en plein jour, tu essaies de le faire la nuit ?
— Devdas (2002)
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)
