Happy Pi Day!

Just so everyone knows the difference between Pi day and Pi Approximation Day. Its an easy thing to confuse. 🙂
Pi Day is observed on March 14 because of the date’s representation as 3/14 in month/day date format. This representation adheres to the commonly used approximation of 3.14 for pi. Whereas the fractional approximation of pi (or 22⁄7) resembles the date July 22 in the day/month format. So Pi Approximation Day is therefore celebrated on July 22.
