There are people who don't celebrate the holiday at all for whatever reason -- I think that's #2. I believe #3 means... "no I don't, but I still celebrate something around this time of year and that something is...." Meaning for the person who selects #3 to tell us about what they do celebrate.
Correct me if I'm wrong here Kokuma.
That's the thing I tried to reach with this poll.
I, myself, celebrate Christmas but more cause of these "non-spiritual" reasons than the christian theme about Christ's birth.
Usually my aunt has come to my dad's place (which was originally my granparents') with her 2 kids and we have spent the Christmas time there together. Now that granny has passed away and aunt has settled to a new house in other province, she isn't coming to there anymore this year and I think it's just me and my dad there this time.
I get all filled up with this Holidays woo-woo (all the decoration stuff everywhere in the stores, holidays songs as grocerystores' bgm music, the hurrying ppl in the streets in hunt for the last presents) many days before the actual 24th/25th day...
I have to evacuate there in dad's ranch around 20th day, empty my head totally and start to build the "Christmas feeling" from, like nothing. I bake ginger snaps and christmas tartlettes, decorate dad's house with Christmas stuff, listen Christmas CDs and go to look for fir-tree in our own forest.
In Finnish tradition Christmas is celebrated in 24th more than in 25th. Santa comes in the 24th evening and brings presents to kids. 25th day is also important, known as the "most holy day of the year".
The elements that make my Christmas are Christmas songs, real woods-smelling tree in the corner of the livingroom decorated with the old worn-out stuff that can be found from cardboard box in carage. Hyacinths, "Christmas Stars" and other seasonal flowers like Amaryllises. Walk in the snowy forest in the 25th day morning just when the sun is rising and it starts to get lightful, as I have done in many years.
The thing that makes Christmas not to feel like "real" Christmas is if there is no snow on the ground like there has been in couple of last years (weather climate change?

).
In finnish we call that situation a "black christmas" - in comperement to white one when there is snow. (Nothing racial included)
