Happy Square Root Day

Square root day is a holiday celebrated on dates where the day and the month are both the square root of the last two digits in the current year. For example, today is March 3, 2009 (3/3/09), and the next square root day will be April 4, 2016 (4/4/16). The final square root day of the century will occur on September 9, 2081. Square root days fall upon the same nine dates each century.
