10 ways to celebrate Pi Day

March 14 (3.14) With the annual holiday coming up soon, here are 10 ways to celebrate Pi Day.

There are holidays, and then there are holidays for nerds, and March 14 (3.14) is one of those. Based on the mathematical constant number that represents the ratio between the circumference and the diameter of a circle, Pi Day has grown to become somewhat of a day to celebrate for mathematicians and techies. Here are 10 things to do on the big day.

Make a pi-themed pie

What tastes better than pie? A pi-themed pie on Pi Day, of course. The process to make a pi-themed pie is similar to the one used to make a regular pie, except one important difference: Reserve some dough at the end to make a pi symbol to slap on top. For complete directions, click here.

Rock a Pi Day T-shirt

Clothing accessories are a great way to show off your Pi Day pride. There’s a variety of pi-themed clothes to wear, including the Super Pi shirt, and shirts emblazoned with scary graphics showing what the world would look like without pi. Or, if you’d like to decorate your car, purchase the “I’d rather be deriving” license plate holder.

Write Pi-kus or Pi-ems

For those of you who are wordsmiths, there are ways to celebrate the day through the written word as well. For example,write a pi-ku or a pi-em, all about pi. NPR asked readers to submit pi-kus in which the first line has three syllables, the second line has one and the third line has four. Here’s one:

Hello Pi


Endless digits

Got one of your own? Leave it in the comments section.

Go on a pi scavenger hunt

Pi is an endless number, so look for numbers that are important to you in it. Search for your birthday, a family member’s birthday or other important dates or numbers in pi. Pi goes on forever, so it’s got to be in there somewhere, right? For reference, click here for a list of the first 1,000,000 decimal places.

See how many digits of pi you can recite

Pi goes on forever, so you can’t possibly recite them all. But, there are contests to see just how far you can go. Can you beat Benjamin Most, who recited 2,552 digits?

Watch “Pi” the movie

If you’re a movie buff, there are ways for you to celebrate too. You can, for example, watch “Pi” the movie. As described by IMDB, it is about “a paranoid mathematician who searches for a key number that will unlock the universal patterns found in nature.”

Listen to Pi music

Musicians at heart have embraced Pi Day as well, by making a variety of songs. Some will help you remember the numbers in pi. Others are catchy jingles that can be played during cocktail parties, as children’s performer David Perry does here.

Tell Pi Day jokes

For the pi-enthusiast pranksters, there are one-liner jokes you can tell on Pi Day. Such as: Mathematician: 'Pi r squared' Baker: 'No! Pies are round, cakes are square!' Or… Question: What do you get when you take the moon and divide its circumference by its diameter? Answer: Pi in the sky.

Celebrate Albert Einstein’s birthday

Pi Day just so happens to also be Einstein’s birthday. So, while you’re at it, pay tribute to the father of modern physics.

Read a book about pi

After a long day of celebrating Pi Day, perhaps all you’ll want to do is sit and read a nice pi book. For that, there are plenty of options, including the biography of Pi and the Joy of Pi. If you have a son or daughter, perhaps they would like to read the story of Sir Cumference and the Dragon of Pi. And, if you don’t want to read about math, there is always the critically-acclaimed Life of Pi book by Yann Martel, which has very little to do with the number.
