# How to Celebrate Pi Day on March 14

March 14 is Pi Day. This date was chosen because it is a celebration of π, a transcendental number, a constant which is approximately 3.14, since the date is generally written as 3/14 in the United States.

The holiday was created by Larry Shaw in 1988, and the United States Congress recognized it as an official holiday on March 14, 2009. We don't get to take the day off, but we can celebrate the day by bringing out our inner mathematician.

More importantly, we can all do our part to make it the next over-commercialized holiday that it is meant to be.

This article presents many ways in which to celebrate Pi Day, and has included ways that you too can commercialize this important holiday.

## Memorize and Recite the Digits

The digital representation of the irrational number π never ends and never repeats. One fun way to spend Pi Day is to memorize and recite the digits of Pi. See how far you and your friends can get, and award a prize to the one who can go out the farthest.

According to Wikipedia, in 2004, Daniel Tammett was able to recite 22,514 digits of Pi. You could try to beat that world's record.

## Have a Pi Day Party

Any day is a great day to have a party, and Pi Day provides a great reason to have one. Whether you take turns rapping out the digits of Pi, or have a pie bake-off, or sit around eating movies and watching movies, or performing mathematical calculations using π, you and your guests are sure to have a great time with ice that is in the shape of π.

## Eat Pie

Traditionally pi day is celebrated with baking a pie. Purchasing a pie is also acceptable. Adding the Pi symbol to the pie is preferable. Without the symbol, it is like celebrating a birthday cake without candles. Using a Pi pie plate adds a special touch to the festivities.

Besides eating pie, you can also eat other circular things like cookies and tortillas. You can also eat things that begin with the letters "pi" like pineapple, pistachios, pinto beans, pizza, and pine nuts.

## Perform Circle Calculations

A great way to celebrate Pi day is to remember and realize the importance of Pi. In Euclidean plane geometry, pi is the ratio of the circle's circumference to its diameter. The result is a constant number.

You may remember from school that π is used to calculate parts of a circle. One exciting way to spend Pi Day is to calculate the circumference, diameter, or area of all of the circles you see.

The area of a circle is calculated by taking π times the square of the radius.

The circumference of the circle is calculated as pi times the diameter.

The diameter of the circle is calculated as 2 times the radius.

To commercialize this endeavor, you could charge people for these calculations, although I am not sure how a large a market there is for circle calculations. Alternatively, you could buy or sell lots of things that are circular.

- Best Movies to Watch on Pi Day

Pi Day is a great excuse to watch a mathematics oriented movie, and this list of math movies will help you find the one that is just right for you to watch on March 14. - Pi Day: Math Goes Pop!

This article analyzes some announcements about Pi Day.

## Walk Around in Circles

The way Larry Shaw celebrated Pi Day is to walk around the circular spaces of the San Francisco Exploratorium where he worked as a physicist. You too can celebrate the day by walking around a circle with a group of friends or coworkers. To make this a commercial enterprise, you can find an especially intriguing circular path, and charge money for people to walk on it.

Since Larry Shaw also ate fruit pies to celebrate the day, selling pieces of pie would add to the commercial value.

## Pi Movies

## Watch Movies

Kicking back and watching movies is a perfectly acceptable way to spend Pi day. Watching movies π is traditional, but you can also watch movies about Pi. The movie Life of Pi is another option.

Watching a movie about mathematics is a great way to bring out your inner scholar and maybe learn a thing or two about math in the process. If you prefer, watching movies about pie will do in a pinch. If you are really desperate, you can even watch movies that start with the letters "Pi", like The Piano or Pink Panther, or Pirates of the Caribbean.

## Albert Einstein Look Alike Contest

Since it is also Albert Einstein's birthday, March 14 is a great way to celebrate his birthday as well. What better way to do that than to have a lookalike contest. You can charge an entrance fee for participation, or charge people to vote on the one who looks most like him.

## Clothing

No day can be complete without the proper clothing and accessories. There is a wide array of π t-shirts and jewelry so you can spend the day in a stylish fashion. You will instantly look smarter, and people may even begin to think that you are smart enough to take apart and fix their computer.

## Books

If you cannot get your friends and family to celebrate Pi day with you, or prefer to celebrate it alone, these books are great to sharpen your math skills and celebrate the festive occasion.

You might even want to read these books throughout the year to continue on the celebration, and have time to gather all sorts of knowledge to spend the next Pi Day being knowledgeable.

There are even books you can buy for your children, so they can become smart, and you can take credit for the genes. This will make you look smarter without the studious effort on your part.

## Creativity

You can spend Pi Day creating the symbol π by using its numerical digits. See how big a symbol you can make.

There are bonus points for writing a computer program which can do this for you.

## Carry the Celebration On Throughout the Year

If you didn't get a chance to celebrate Pi Day, or simply want to continue the celebration, the approximate fraction of π is 22/7, so you can also celebrate Pi Approximation Day on July 22.

We can also look forward to 2015, when on Pi Day at 9:26:53, the date will be 3/14/15 at 9:26:53, corresponding to 3.141592653.

## Celebrate Pi Day

As you can see, there are many fun and exciting ways you can celebrate this important holiday that commemorates the mathematical symbol, π. By using circular shapes and things that start with the letters "pi" you are well on your way of celebrating this important occasion.

Purchasing t-shirts, ice cube trays, and pencils that include the symbol π are an important step of commercializing this holiday, and in looking like a mathematical genius.

My house is next to a school. I am going to make a poster saying Happy Pi Day and hang it on my fence. I love Pi Day!

Very interesting hub, great tips for Pi Day. Is it acceptable for us from other countries who write the date 14/3 to still celebrate it? Voted up.

This is very insightful information as my daughter is studying this concept in math. I can't wait to show her! This is a very timely message! Thanks Millionaire Tips! Voted interesting and Useful.

I am not a math person, but this just tickles me!

Four days to go before this year's celebration begins! Thanks for the reminder to send my grandchildren a Happy Pi Day note. Your ideas for celebrating are really fun ones. One of my favorite AE quotes is, "The difference in genius and stupidity is that genus has its limits." Another is, "A clever person solves a problem, a wise person avoids it." And we can't forget, "Creativity is intelligence having fun." :) Now I have to go think about what kind of creative pie to make… Have fun on the big day at your house!

We are almost there again. I have a great idea for dinner. Pi shaped potatoes or maybe cookies. My family will die laughing.

I still love this hub.

Check out the activities at your local school and library. My children's school has activities to celebrate Pi Day.

Any excuse to eat pie is good enough for me! Wowee, such research. For those of us who cannot add, this is all way way, way beyond us, so way beyond in fact it reaches into fun stratospheres! Clever to name three films beginning with Pi. Feel like a game of scrabble?

Even before I read this, I was already thinking that the date 3/14/15 will be really cool. Then I saw the time reference and it was all over: I love pi!! :D I was almost a math major, and though I decided against it, I will always love my beloved pi. :)

Cheers to Pi celebrations everywhere! Shared on FB and will put the day on my while board.

Pi Day has been on my white board calendar since the beginning of the month. My middle school kids are going to take a few pies to school tomorrow (guess what I will be doing tonight) To celebrate. Fun, awesome hub!

maybe we can institute the first ever half day off in honor of pi day - a small suggestion from Kim's other half - Will

Kim loved this so much she shared it with me- too funny!

I love your humor. Voted up and funny.

Now, this is an unusual holiday that I'd love to celebrate. I love the pie-eating suggestion, especially with the symbol. Voting this Up and Interesting.

Hysterical! I love it; any reason to celebrate. However, mathematics is not my strong suit so I think I will celebrate with a "pie" on PI DAY!

Excellent hub, voted up and interesting.

very good hub! I didn't even know there is something like the Pi day. this is even of special interest for me because I am really into maths and it is nice to see there is a Pi day!

I will make a Pi Pie for Pi day :P

Voted Up and Awesome and shared wherever I can!!
