Happy Square Root Day!

Today is Square Root Day! It happens only 9 times every century.

So it works like this: It happens when the day and the month are both the square root of the last two digits of the year.

Since today is 03/03/09, three is the square root of 9, and works. The next Square Root Day will be April 4, 2016.

Although this is a ficticious holiday, some people are actually taking it seriously! A math teacher in California is actually going to give $339 USD to the person who puts on the best Square Root Day celebration. I'm assuming he's going to be the judge.
