What are you doing for Christmas?

Just wondering how Americans (and people from other countries where Christmas is a holiday) celebrate Christmas. I heard that this is the time when Christmas preparation is the busiest in my textbook for this exam. Not sure if I’m right. What are you doing for the preparation? What are you buying? What activities are involved? I’d like to know how you jellies are enjoying the holiday.

This thread will be opened until the end of Christmas season (January 6, am I right?) I’ll take it as an opportunity to learn more about the Western jellies.
