FRESNO, CA (KMJ) – It’s pi day – 3.14.
The earliest known celebration of pi day was organized by a physicist in 1988 at the San Francisco Exploratorium.
March 14 used to be a holiday for just mathematicians as both the date (3/14) and the value of pi – the ratio of the circumference of a circle to its diameter – begin with the digits 3.14.
Even NASA is getting in on the pi fun.
For the fourth year in a row, the agency’s Jet Propulsion Laboratory has created a pi day challenge featuring math problems NASA scientists and engineers must solve to explore space.

If that’s too heady…just enjoy a slice of pie in honor of the day. Many restaurants offering discounts for you to do so, selling pies for $3.14.
