when does elf on the shelf show up

The elf on the shelf tradition typically begins on the night of December 1st, when families place their elf in a new spot around the house each day. Some families also enjoy reading the accompanying storybook and playing games related to the tradition. The elf is often a playful and mischievous creature who can report back to Santa Claus about the children's behavior throughout the month. However, the specifics of the tradition may vary by family and location.
