A holiday honoring a math constant may not seem very exciting. But Pi ("π") Day, observed annually in the US on March 14 (3/14), is an exception. The celebrations usually begin with activities centered around Pi — the ratio of the circumference of a circle to its diameter — widely recognized as 3.14. However, they usually end with a slice or two of delicious pie.
