Happy Square Root Day!

I bet you had no idea that this was Square Root Day, ok I didn't know until I saw it on the news this morning, but if you look at the date: 3/3/09, you can see it makes a square root (3x3=9). This only occurs four times in a given century - 3/3/09, 4/4/16, 5/5/25 and 6/6/36.

So call your friends and neighbors, or wait another seven years to celebrate Square Root Day.
