I have a sentence:
Happiness is drinking a glass of champagne on a hot summer afternoon.
So I'm thinking if we want to say the same about night do we have at night or on [article] night?
I know we say in (the afternoon / the evening / the night) when we mean 'during this period of time'. Correct?
But what is the difference between on and at? Could we use articles with on\at and night?
