Pi Day

By Vlado

Pi Day is an annual celebration commemorating the mathematical constant π (pi). Pi Day is observed on March 14 (or 3/14 in the month/day date format), since 3, 1, and 4 are the first three significant digits of π in decimal form. In 2009, the United States House of Representatives supported the designation of Pi Day.[2]
Pi Approximation Day is observed on July 22 (or 22/7 in the day/month date format), since the fraction 22⁄7 is a common approximation of π, which is accurate to two decimal places and dates from Archimedes.[3]
A sequential time will occur on 3/14/15 at 9:26:53.58979... following the sequence of pi to all digits.[4]
