Me thinks that in terms of dates
"in" refers to a measurable extent, such as an hour, a year, etc.
Example: See you for Easter in 2004!
"on" refers to the surface of a calendar.
Example: See you on Easter Monday!
"at" refers to a general point in time, such as "Christmas", "Easter", etc.
Example: See you at Easter. (general point in time)
Example: See you on Easter Day. (specific day)
See you on Easter Island?

See you on Easter Island at Easter on Easter (day) in my Easter ears. :D
I'll be in my Easter bunny suit.
Which is correct?
I have a question
so should you say, on Christmas day? or at Christmas day?
On Christmas day
At Christmas = the general period
