Today Is Square Root Day

For example, today is 3/3/09. That combination would make it a Square Root Day. The next one will be in seven years, which will be 4/4/16. The following one will be in the year 2025 on May 5th: 5/5/25. You already follow the logic.

Apparently the Square Root Day is a some kind of a Holiday. At least that's what CNet calls it.

"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."

The public is very excited about the Square Root Day. Here are some responses from Twitter.

walstini: Watching math vids on the youtube and digging March - today is a square root day, then pi day, then St. Paddy's. A fortnight of parties.

andrewmoizer: Happy "Square Root Day" (from date 3/3/09). However, I'm a contrarian, like Perfect Squares & write dates 09/3/3 so Happy Perfect Square Day
