March 14th is Pi Day worldwide.

This yearly celebration commentates the mathematics constant π (pi), the ratio of the circumference of a circle to its diameter. In US digit format, March 14 is 3/14. The first three digits of pi are 3.14.

Being an irrational number, π cannot be expressed exactly as a common fraction. Consequently, its decimal representation never ends and never settles into a permanent repeating pattern. The digits appear to be randomly distributed, although no proof of this has yet been discovered. Also, π is a transcendental number – a number that is not the root of any nonzero polynomial having rational coefficients. The transcendence of π implies that it is impossible to solve the ancient challenge of squaring the circle with a compass and straight-edge. [1]

The earliest known celebration of Pi Day was organized by Larry Shaw in 1988 at the San Francisco Exploratorium. The Exploratorium continues to hold Pi Day celebrations.

On March 12, 2009, the U.S. House of Representatives passed a non-binding resolution (HRES 224), recognizing March 14, 2009, as National Pi Day.
