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 Day is an annual opportunity for math enthusiasts to recite the infinite digits of Pi, talk to their friends about math, and eat pie.

Pi has been calculated to over 50 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.

Pi Day is on March 14, and any day that combines fun, education, and pie is a day worth celebrating! Pi, also known by the Greek letter “π,” is a constant value used in math that represents the ratio of a circumference of a circle to its diameter, which is just about 3.14….15…9265359… (and so on). Not only that, but the fourteenth of March is also Albert Einstein’s birthday, so all together it’s nothing short of a mathematician’s delight.

National Pi Day is annually celebrated on the 14th of March. It was also decided as the International Day of Mathematics by UNESCO’S fortieth General Conference on 19th November 2019. This day is to celebrate the mathematical constant pie. It has an approx. value of 3.14.

You can observe National Pi Day by eating pies and other circular treats. Pi and pie are English homophones, and the coincidental circular form of pie makes it the best treat of the day.

If you love Mathematics, mark the day by holding a pi memorization contest with friends. Although pi can be calculated to infinite numbers, figure out who among your friends can recite most of the numbers as they follow each other. Google has a training app for the same to help you in the contest.

Another great way to mark this day is by celebrating Albert Einstein’s birthday. You can attend celebrations in Princeton, New Jersey where a major event to mark the pi day and Einstein’s birthday is held. Some of the Pi Day activities you can take part in during the event include dressing like the Nobel Prize winner. If declared the winner of the Einstein’s Look-Alike contest then you will be lucky to go home with a great award. The German-born theoretical physicist lived in Princeton for 20 years while working at one of the institutes there.

Dang. I missed Pi(e)day!
