at night – by night - in the night

Hello,
I am at a loss – which is correct:
a) I can’t get used to working at night (from 11 p.m. till 6 a.m.)
b) I can’t get used to working by night.
c) I can’t get used to working in the night.

When is each of them used?:roll:
Would be grateful for your help.

at night:(11-6 am).
by night:until night. until 11 may be.
no idea about the third sentence

At night and in the night are both good. By night is a little more complicated as there I have heard some variations between AE and BE and also regionally in the UK.

I have not heard it used in the sense of until a certain time, but I wouldn't be surprised if this is common to other native speakers. Phrases like "travelling by night" and "working day by day" are very common. In your example I think 1 and 3 are the best.

Tnx, everybody.
Could you also have a look at this:
We never used to lock the door in the daytime (by day??).
Thank you

I would use in the daytime or during the day, but see no problem with by day.

Thanks, Davy
