Pi denotes the relationship between a circle’s circumference and its diameter and is denoted by the fraction 22/7 which calculates approximately to 3.14. One of the most widely recognized mathematical constant, π, is an irrational number, the digits of which repeat in a random fashion and are never ending.

Depends on Date Format

People in countries that write their dates in the date/ month format celebrate Pi Approximation or Casual Pi Day on 22 July or 22/7. On the other hand, those who write their date in month/ date format celebrate Pi Day on March 14 (3/14 or 3-14) because the first three digits of the date correspond to the first three digits of pi - 3.14.

Move to Replace Pi

In recent years, some mathematicians and physicists have argued for the replacement of the π by tau and to celebrate Tau Day on June 28 instead of celebrating Pi Day or Pi Approximation Day.

How to Celebrate?

Here are some ways you can celebrate this irrational, but fun holiday:

Celebrate the day with lots of pie – remember a pie is also a circle so not only are you learning something about math, but also having fun while eating it!
Have a pi contest. Whoever knows the most digits in the number takes home a pie.

Did You Know...

...that the sequence 123456 does not occur in the first million digits of pi?

I didn't enlist in the Army -- I was drafted. So I wasn't going to make life easy for anyone. During my physical, the doctor asked softly, "Can you read the letters on the wall?"

"What letters?" I answered slyly.

"Good," said the doctor. "You passed the hearing test."

There are people who have green thumbs. And then there's me, Ms. Black Thumb. I didn't think anyone else noticed until the day my sister visited.

"I found this in the yard," she said, handing me a potted plant as she came in the door. "I think the wind blew it off your deck."

"It wasn't the wind," my husband joked. "It jumped."

My brother delivered prescriptions to people too ill to go out. Since the neighborhoods he visited were often unsafe, he decided to get some protection.

"Why do you need a pistol?" asked the clerk at the gun shop.

My brother had to explain, "I deliver drugs at night and carry a lot of money."

Shortly after the FAA announced the ban on fluids, my husband was stopped by airport security because they found a bottle of water in one of his carry-on bags.

"Sorry," the officer said, tossing the bottle into a bin of confiscated items, "but water is now considered a liquid."
