Searching the 12 Days of Christmas - Need Ideas

I am looking for some kind of activity or a tradition for the 12 days of Christmas. I like to bask in the Christmas glow and want to continue to celebrate or practice Christmas cheer for the 12 days. Any ideas? Do I close a door on Advent calendar each day? That seems kind of sad. Besides there are 25 days on an Advent calendar, and only 12 days of Christmas. I can't exactly send a true love 10 lords of leaping or some such thing.
