Today is the day Seinfeld fans clamor for every year. Or, well, at the very least, it happens and they think oh cool, it's here! No matter what type of fan you are, today is Festivus- the made-up holiday made famous by the iconic NBC series, specifically by George Costanza's father, Frank (Jerry Stiller). Since the holiday was popularized back in the '90s, people have actually begun to celebrate it. And being that this is the age of social media, Twitter and Instagram are soaked in Festivus cheer.

So, move aside, Merry Christmas and Happy Holidays, because today is Festivus ... for the rest of us!

First things first, let's start at the beginning. What is Festivus?

And here's the celebration:

The #Festivus have begun!

While comedian Jerry Seinfeld has yet to post anything to his Twitter or Instagram accounts regarding the Festivus holiday – which we're sure he will eventually – our guess is he's too busy calming down from the exciting announcement from this past Monday. On Dec. 21, Seinfeld dropped the trailer for the newest season of Comedians in Cars Getting Coffee. And while there are a slew of comedians to look forward to, there's one guest creating a lot of headlines: President Barack Obama.
