Square Root Day

I have been reminded that today is one of those days when you can do mathematics with the date. In this particular instance the day and the month are the same and when multiplied together they make the year. Well, only if we consider the last two digits of the year. To be specific if we write today's date as 03/03/09 then we can see that 3 x 3 = 9. There are only nine dates that exhibit this property each century so enjoy square root day while it lasts, it's another seven years until the next one.
