Well, the title is pretty self-explanatory, but just for the sake of clarity, answer in the way that makes sense to you. The tradition doesn't have to be uniquely atheist; it just has to be one that has some personal significance.
If you have none, perhaps there is a tradition you would like to start. Despite the widely varying views on Christmas itself, I think it's a good time to take a break and enjoy something ceremonious (more or less). I think traditions are healthy provided people know when to let go of them.
like I've said already in this group, I celebrate the pagan roots of the "holiday" with my fiance.
so a decorated tree
red and green candles
and stuffing you're face is great.
then there is Odenclause. that's right. Odenclause. lol he is the pagan god that Santa Clause impersonates every year.
my fiance told me about a tradition that she used to do when she was little, and when we have kids, I deffinetly want to keep that tradition. apparently when you get done with the cardboard tube that has wrapping paper rolled on it, you decorate it and use it as a horn to call the reindeer. lol shut up, it's cute.
My kids are grown now, and don't have kids of their own yet, so most of our pre-Christmas traditions have gone out the window. No one wants to bake cookies anymore, everybody ditches me when it comes time to decorate, lol. I honestly could just skip it all, except for the fact that everyone would be disappointed. Nobody believes in god or Jesus in my family anymore, anyway. It seems silly that we celebrate his birth. But we do it every year, anyway. What am I going to do with all those decorations, otherwise? I guess its a celebration of family and love and getting fun presents. I wish I could come up with a better name for it other than christmas.
I'm Bill so I call it Billmas, I guess you would call it Lismass...I still put up a tree for my daughter, she believes in Santa, Toothfairy, and The Easter Bunny...And Goblins at Halloween, must be a Really fun time for her, too long ago for me to remember..lol
