This annual celebration is always on March 14th and commemorates the mathematical constant of Pi (π). It is celebrated on 3/14, as it signifies the three most significant digits of Pi in the decimal form: 3, 1, and 4.
How to celebrate Pi Day? There are lots of ways, throwing pies, discussing the significance of the number...or just including eating pie.
And here’s a fun fact – MIT (Massachusetts Institute of Technology) has often mailed its application decision letters to prospective college students for delivery on Pi Day! Starting in 2012, MIT has posted its application decisions on a private website on Pi Day, exactly at 6:28pm. They have deemed this “Tau Time,” which is in honor of the rival numbers Pi and Tau.
Pi has been mathematically calculated to over one trillion digits beyond its decimal point! Pi’s infinite nature makes it a fun concept to celebrate and study.
