Pi Day

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. It is usually celebrated at 1:59 PM (in recognition of the six-digit approximation: 3.14159). Some, using a twenty-four-hour clock rather than a twelve hour clock, say that 1:59 PM is actually 13:59 and celebrate it at 1:59 AM or 3:09 PM (15:09) instead. Parties have been held by the mathematics departments of various schools around the world. Source: Wikipedia Tags: Mathematics, Humor, Gr33n Data
