What is Festivus?

You don’t have to tell “Seinfeld” fans what today is: It’s Festivus!

“Seinfeld” fans have been uploading their Festivus traditions across all social platforms. The holiday is celebrated Dec. 23 and serves as an alternative to the commercialism of Christmas.

The actual inventor of Festivus is Dan O’Keefe. His son, Daniel, was a writer on “Seinfeld” and appropriated a family tradition for an episode.

Here’s a look at how others are getting into the Festivus spirit just like Jerry, George, Elaine, Frank and Kramer:

Happy Festivus, although I don’t have many grievances seeing as I’m a World Champion

"The tradition of Festivus begins with the Airing of Grievances. I got a lot of problems with you people! Now you're gonna hear about it!" ~ The great Frank Costanza #Festivus #AiringofGrievances #Seinfeld pic.twitter.com/hScNWGdwBW

With thousands of trees planted, we've got NO PROBLEMS with you people. But in the spirit of #Festivus, we still have grievances to "air."
