Oh, what fun! Can I open the door today?
An Advent calendar is a card or poster with twenty-four small doors, one to be opened each day from December 1 until Christmas Eve. Each door conceals a picture related to the Nativity story.
This popular tradition arose in Germany in the late 1800s and soon spread throughout Europe and the Americas. In 1904 an Advent calendar was inserted in the newspaper Neues Tagblatt Stuttgart as a gift for readers that continued annually for years.
