Definition
The period of darkness between sunset and sunrise. It can be used as a noun ('at nighttime') or as an adjective ('nighttime activities'). It refers to the time when it is dark outside.
Usage & Nuances
Can be written as one word ('nighttime') or two ('night time'), but the one-word form is standard in American English. 'At night' is more common in everyday speech than 'at nighttime.' As an adjective, it's always one word: 'nighttime driving,' 'nighttime routine.'
