“Pi Day is celebrated on March 14th (3/14) around the world. Pi (Greek letter “π”) is the symbol used in mathematics to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159.
Pi has been calculated to over one trillion digits beyond its decimal point. As an irrational and transcendental number, it will continue infinitely without repetition or pattern. While only a handful of digits are needed for typical calculations, Pi’s infinite nature makes it a fun challenge to memorize, and to computationally calculate more and more digits” (http://www.piday.org/).
This year is particularly special Pi Day. As mentioned above, pi is approximately equal to 3.141592653. This year is 2015 making the date an even more exact pi than other years, 3/14/15 9:26:53. So at 9:26 and 53 seconds, there will be an exact match for pi’s first 10 digits. People are calling this day the “Pi Day of the Century” since it will not happen again until the year 2115. Some are even preparing to eat pie at both 9:26:53 a.m. and 9:26:53 p.m. to celebrate this occasion due to the homophone.
