Are there any jellies who don't celebrate any of the religious or cultural holidays this time of year?

I was raised Catholic so of course we celebrated Christmas, now I am a grown-up and my faith does not celebrate any holidays this time of year. Baha’i’s celebrate Ayyam-i-Ha at the end of February. I don’t think I feel like I am missing out, but I do kind of feel like I am on the outside looking in. I am interested in hearing stories from others who experience this season without any celebrations.
