Square root day is a humorous holiday celebrated on dates where the day and the month are both the square root of the last two digits in the current year.[1] For example, the last square root day was 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. These goofy holidays can also be referred to as “Squared Day,” as the date written out is like a mathematical equation. 03 x 03 = 09 (03.03.09)
