The tradition of Festivus begins with the airing of grievances.

Each year on December 23rd, Festivus commemorates a holiday episode of the television comedy, Seinfeld. In 1997, the popular television comedy brought Festivus to the masses when Frank Costanza (played by Jerry Stiller) explains he invented the holiday in response to the commercialism of Christmas. Its slogan is "A Festivus for the rest of us."

Festivus traditions derived from the television episode and the original creator have been combined over the years.
