3. Differences between in, on and at

Sometimes more than one preposition can be used to introduce the same time expression. However, the meaning will be slightly different.

My grandparents visit us on Christmas Day.
In this case we are talking about a specific day (December 25th).
I buy a lot of presents at Christmas.
En este caso se habla de un período de tiempo en general (la Navidad).
I didn't sleep well in the night.
In this case we are talking about what happened during a particular night when this girl couldn't sleep.
Nightclubs open at night.
In this case we are talking about an action that usually happens at night (the discotheques are open).
The expressions of time introduced by a preposition of time can be placed both at the beginning and at the end of the sentence. However, in English it is much more common to find them at the end:
In the morning, I usually go to school.
I usually go to school in the morning.
