Please, explain it for me. i don't understand prepositions with Christmas.

on christmas day
on christmas eve

Of course, there are situations in which you may use any other preposition, but in this case in particular, specifying days, it shall be 'on'.

Use on for specific days:

I'll visit Mum on Christmas Day
I'm sure to be drunk on New Year's Eve

Use in for a range of days, similar to "during":

I'll visit Vietnam in the Christmas holidays.
I'll visit Vietnam during the Christmas holidays.
In my retirement, I want to grow flowers.
During my retirement, I want to grow flowers.

Use at for specific times:

The match will start at 3pm.
Look toward the northern horizon at sunset.

I'm not an expert, but that's how I would use them!
Hope that helps.
