Count on Tuesday's alignment of the calendar to add some excitement to the lives of at least a few math geeks.

Tuesday 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.

"These days are like calendar comets, you wait and wait and wait for them, then they brighten up your day--and poof--they're gone," Ron Gordon, a Redwood City, Calif., teacher who organized a contest intended to publicize the event, told the Associated Press. The prize, or course, is $339.
