“Pi Day” – 314
March 14 — or 3/14 — celebrates the mathematical constant of pi. Pi represents the ratio of circumference of a circle divided by its diameter. While it is often abbreviated as 3.14, pi has an infinite number of digits beyond the decimal point, starting with 3.141592653.
One celebration was 3/14/15, perfectly matching the first numbers past the decimal point of pi. “Pi Day.”
