Christmas is cool in the same way
Easter or
Winter is, IMO. My mother has cousin who was born around
Christmas who is called
Mary Nollaig (Nul-ig). Nollaig is the Irish for
Christmas and
Noel. I thought this was very funny the first time I heard it. Incidentally my mother was born in December and her mother considered calling her
Carol or
Noelle.
Nollaig is not that rare as a first name though - it is used for men and women.
