A fun way to count down the days of the Advent season, our old-time advent calendars are a fun holiday activity for the entire family. How do you use an advent calendar? Starting on December 1st, you open the first of the sequentially-numbered little tabbed "doors", and so on, until you arrive at the final door on December 24th to reveal a special Christmas Eve nativity picture. Children love searching each morning for that day's numbered "door", and discovering what surprise holiday picture or text lies hidden behind it.
