Pi Day is celebrated on March 14th (3/14) around the world. Pi is the symbol used in mathematics to represent a constant - the ratio of the circumference of a circle to its diameter - which is approximately 3.14159.

Pi has been calculated to over one trillion digits beyond its decimal point. As an irrational and transcendental number, it will continue infinitely without repetition or pattern. While only a handful of digits are needed for typical calculations, Pi's infinite nature makes it a fun challenge to memorize, and to computationally calculate more and more digits.

The earliest known official or large-scale celebration of Pi Day was organized by Larry Shaw in 1988 at the San Francisco Exploratorium with staff and public marching around one of its circular spaces, then consuming fruit pies. The Exploratorium continues to hold Pi Day celebrations.

March 14 is also Albert Einstein's birthday.

The first calculation of pi was done by Archimedes of Syracuse (287-212 BC), one of the greatest mathematicians of the ancient world. For further interesting facts about pi, visit this website:
