Pi Day is an annual celebration commemorating the mathematical constant π (pi). It is observed on March 14 (3-14) since 3, 1 and 4 are the three most significant digits of π in decimal form. In 2009, the United States House of Representatives supported the designation of Pi Day.
The number π is a mathematical constant. It is the ratio of a circle's circumference to its diameter, which is approximately equal to 3.14159. It has been represented by the Greek letter "π" since the mid-18th century though it is also sometimes spelled out as pi.
The town of Princeton, New Jersey, hosts numerous events in a combined celebration of Pi Day and Albert Einstein's birthday, which is also March 14. Einstein lived in Princeton for more than 20 years while working at the Institute for Advanced Study. In addition to pie eating and recitation contests, there is an annual Einstein look-alike contest.
Many of us are looking forward to next year when Pi Day will have special significance on 3-14-15 at 9:26:53 then the date and time represent the first 10 digits of π!
