Fun Observances

Pi Approxmation Day

July 22 is Pi Approximation Day. Also known as Casual Pi Day, the day is dedicated to the mathematical constant pi (π).

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 was once a legal secretary to a young law clerk who passed the bar exam on his third try. This fledgling attorney worked hard on his initial pleading, which should have read "Attorney at Law" at the top of the first page.

After I submitted the finished document for his review and signature, I was embarrassed when he pointed out a critical typing error. "Must you rub it in?" he asked.

I had typed: "Attorney at Last."

As a judge, I was sentencing criminal defendants when I saw a vaguely familiar face. I reviewed his record and found that the man was a career criminal, except for a five-year period in which there were no convictions.

"Milton," I asked, puzzled, "how is it you were able to stay out of trouble for those five years?"

"I was in prison," he answered. "You should know that—you were the one who sent me there."

"That's not possible," I said. "I wasn't even a judge then."

"No, you weren't the judge," the defendant countered, smiling mischievously. "You were my lawyer."

As a potential juror in an assault-and-battery case, I was sitting in a courtroom, answering questions from both sides. The assistant district attorney asked such questions as: Had I ever been mugged? Did I know the victim or the defendant?

The defense attorney took a different approach, however. "I see you are a teacher," he said. "What do you teach?"

"English and theater," I responded.

"Then I guess I better watch my grammar," the defense attorney quipped.

"No," I shot back. "You better watch your acting."

When the laughter in the courtroom died down, I was excused from the case.
