I mean

As someone raised in an Agnostic/Atheist household, but whom is surrounded by family and friends of faith, it's just an enjoyable holiday to spend with family and to reach out to friends. Giving feels great and when applicable getting can be nice too.

I've also been informed by my more religious friends Jesus was actually born in spring and the holiday's genesis is more or less an early celebration to get people through the grim bitterness of winter.
