I almost forgot it was π (Pi) Day. Per https://www.timeanddate.com/holidays/fun/pi-day, time to celebrate Pi Day by eating lots of pie.
Celebrated in countries that follow the month/day (m/dd) date format, because the digits in the date, March 14 or 3/14, are the first three digits of π (3.14), Pi Day was founded by Physicist Larry Shaw in 1988.
Pi Approximation Day
Because everyone should be able to enjoy a fun mathematical holiday, people in countries that follow the day/month (dd/m) date format honor pi on Pi Approximation Day. The date of Pi Approximation Day – July 22 – when written in the day/month format or 22/7 corresponds to the fraction (22/7) that pi is usually depicted as.
There are many other days during the year when one can honor pi. Some of these are:
- March 4: The day marks the passing of 14% of the 3rd month of the year.
- April 5: By this day, 3.14 months of the year have passed.
- November 10: The 314th day of the year (November 9 in leap years).
