Today is Square Root Day

Today is Square Root Day, a rare holiday that occurs when the day and the month are both the square root of the last two digits of the current year. Numerically, March 3, 2009, can be expressed as 3/3/09, or mathematically as √9 = 3, or 3² = 3 × 3 = 9.
Square Root Day occurs only nine times in a century. The last one occurred on February 2, 2004, and the next will occur in seven years on April 4, 2016.
