Since give or take 1988, on March 14th, we celebrate one of the most famous numbers in the world — 3.14159... you know the rest.
We celebrate pi because it's an incredible sequence of math—in a world where hard, finite fixtures of truth typically rule the day, in pi, we have an "irrational" number, a sequence that extends into infinity. From its theoretical implications to its practical applications, pi is a fascinating, incredible thing to behold.
But its 2018, so like everything else, it's mostly just another reason for brands to shoehorn "deals" for their products into your social feeds, into your face, and thus, Pi Day is truly for deals. Here are the most inane ways companies are trying to get people to fork over their hard-earned green on Pi Day:
Yes, brands love playing the "pie" / "pi" wordplay games. As such, there is pie. Ostensibly, free pie. For example, the Grand Traverse Pie Company gives you a free slice of pie with every purchase, Boston Market gives you free chicken pot pie, and Pizza Nova is offering pizza pie for just $3.14.
It's #PiDay! Purchase any pizza slice for $3.14 - in store only! Available from open til close, valid TODAY only. RT this post for your chance to win a $25 gift card! Find a location: https://t.co/H7jLcu12Bu pic.twitter.com/JW3jdH8eeR

Great. Now let's see if the brilliant marketers charged with the aforementioned efforts can come up with anything good for Tau Day. Stay woke, pi shillers.
3/14/18 4:12 PM Editor's note: A previous version of this piece stated that we have been celebrating Pi Day since 2009. That is the year in which Congress made the "holiday" official, but it was first popularized by physicist Larry Shaw in 1988. We don't know exactly when you started celebrating Pi Day, but either way we apologize for the error.
