Pi moment of your life!

"Pi Day is observed on March 14, because of the Ancient Greek mathematician Archimedes' first rough approximation of π as being 3.14. (A few years later, Archimedes was able to calculate a much better approximation of π.) However, 22/7 is actually a closer approximation of π than 3.14 is. Thus, a more "accurate" Pi Day could be found in the more common calendar, 22/7, or July 22.
Sometimes the so-called Pi Minute is also commemorated. This one occurs twice on March 14 at 1:59 a.m., and 1:59 p.m. If π is truncated to seven decimal places, it becomes 3.1415926, making the Pi Second occur on March 14 at 1:59:26 a.m. (or 1:59:26 p.m.). If a 24-hour clock is used, the Pi Second occurs just once yearly, on March 14 (3/14) at 1:59:26.
On March 14, 2016, the American way of writing the date (MM/DD/YY) will reflect five digits of pi (3/14/16) (π ≈ 3.1416) rather than three. The year before that, there will be a Pi Second accurate to 10 digits (3/14/15 9:26:54)."
