We have a few -
Our town has a festival where we gather together and sing carols, ending up at the park and having the big pine tree there lit. Little kids put on performances and Santa arrives in the fire engine.
We go every year to the Dickens Fair in San Francisco, too. I get a good discount from a friend who performs there. Lots of fun going to the olde timey shows, dancing and singing and looking at all the pretty stuff.
We have a skinny old fake Christmas tree that I've had for over 25 years. It's only about 3 feet tall, but we have fun sticking it up and decorating it. We call it our "Charlie Brown Christmas tree."
DH and I have stayed up and watched "It's a Wonderful Life" on Christmas eve while wrapping dd's gifts. Now she's older and there aren't so many little things under the tree - maybe we'll all watch it together. We are going to be joining a church in our new town, and I hope they have a Christmas Eve service. (There is no church in our current town that is a good match for us.)
We have a fancy (home-cooked) dinner on the eve, and then a big Christmas brunch. No Christmas day dinner - we go on a hike, then start getting things cleaned up. Then we gear up for our big New Year's bash.
This year will be different; we are having our party on the Solstice, as we will be all moved by Christmas. It's going to be a crush, getting everything done (not so simple - but we must have a holiday party!) And I don't know what we'll do for New Year's Eve - maybe start a new tradition!
