March 14, 2015, (3/14/15) will take on a significance that is most unusual. Normally, people acknowledge 3/14 as “Pi Day,” because those numbers are the beginning of the irrational number, pi, from the Greek alphabet.
Today, at 9:26:53 a.m. and p.m., the date and time will represent the first ten digits in pi, this number-without-end. At those two moments, the number sequence will be 3.141592653.
