what day does elf on the shelf come back

Elf on the Shelf is a beloved Christmas tradition that begins on the day after Thanksgiving. During this time, Santa's helpers, known as elf elves, are sent to families all around the world to help spread holiday cheer and keep a watchful eye on children to report to Santa. The elf elves spend the night before Christmas reporting to Santa on children's behavior, then return to their homes to deliver their report on Christmas morning.
