March 14 is Pi Day in the US (Credit: Flickr/ Public Domain)

A holiday dedicated to a math constant might not sound thrilling. But Pi ("π") Day, celebrated annually in the US on March 14 (3/14), is an exception. The festivities usually start with pi-themed activities to celebrate the ratio of a circle’s circumference to its diameter (approximately 3.14). But they almost always end with a delicious slice of pie.
