If you were a science nerd in high school or college, you know all about pi day! Pretty sure it was just an excuse to eat pie. . .
The exact definition from Wikipedia. . .
Pi Day is a holiday commemorating the mathematical constant π (pi). Pi Day is celebrated on March 14 (or 3/14 in month/day date format), since 3, 1 and 4 are the three most significant digits of π in the decimal form. In 2009, the United States House of Representatives supported the designation of Pi Day.
Have a great Pi day! 🙂
