Pi Day: a quantifiably wonderful excuse to eat pie
Since the number Pi begins with 3.14, people celebrate Pi and mathematics in general on March 14 (3/14) every year.
Here's what you need to know:

Here is the equation that always equals Pi:

and d = the diameter of the circle.
More Fun Pi Facts:
Pi is considered an "irrational" number because it has an infinite number of decimal places that never repeat or form a pattern.
Pi is a "transcendental" number because it is not algebraic.
Pi is a "mathematical constant" because it's always the answer you get when you divide the circumference of any circle by the diameter. No matter the circle, this mystifying number is always the same.
