	Pi Day - Wikipedia, the free encyclopedia
		March 14, written 3-14 in the USA date format, is an unofficial celebration for Pi Day derived from the common three-digit approximation for the number π: 3.14.
		Another day of approximation is on the 355th day of each year at 1:13pm, based on the approximation value of 355/113 derived by Zu Chongzhi.
		Another Pi Approximation Day is November 10 (or November 9, depending on whether it is a leap year or not.) This is the 314th day of the year on the Gregorian calendar.
