"It is night."

Translation: Det är natt.

[patoquac]

In another item it appears as "kväll" can mean evening or night, but here it's rejected.

[PhilipLean]

that other usage might be different, the only translation for kväll as a standalone appears to be ¨evening¨. There is day name + evening = that day's night eg lördagskväll Saturday night,

[Arnauti]

I agree. Kväll only means 'evening', it's night that is ambiguous in English and can mean both 'night' and 'evening' depending on context.

[Gobbert]

What is the distinction between evening and night?

[ThePet081]

Kväll can be late evening, while Natt is the time when you'd be sleeping.

[mollydot]

Kväll was accepted for me.
