Nearly slipped by...this is "Square Root Day" celebrated by math aficionados. It is a rare mathematical function event that won't happen again until April 4th, 2016. Tuesday is "Square Root Day", a holiday that occurs when the day and the month are both the square root of the last two digits of the current year. Previous dates were: 1/1/01, 2/2/04, 3/3/09, 4/4/16, 5/5/25, 6/6/36, 7/7/49, 8/8/64, and 9/9/81. Ron Gordon, a Redwood City, California high school teacher, created the first "Square Root Day" on September 9th, 1981 [9/9/81].
