For me and 1poorlady, it's a few days off work. Keep in mind that 1pl is Christian. But she rightly points out that it isn't really Jesus' birthday, and that it is in fact just a pagan holiday with various pagan traditions (e.g. the Christmas tree, Santa Claus, etc). It is therefore very anti-Christian to observe it. (She won't go as far as to say "not real Christians", but she does say "false religion" sometimes.)

I can take it or leave it, myself. Though I dread the onslaught of Christmas music that is hanging over us like the Sword of Damocles.
