Square Root Day

Postby dwana01 » 2016-04-04 11:14

Square Root Day is celebrated on days when both the day of the month and the month are the square root of the last two digits of the year.

For example, the Square Root Days in this century are;
1/1/01 (January 1, 2001)
2/2/04 (February 2, 2004)
3/3/09 ( March 3, 2009)
4/4/16 (April 4, 2016)... TODAY
5/5/25 (May 5, 2025)
6/6/36 (June 6, 2036)
7/7/49 (July 7, 2049)
8/8/64 (August 8, 2064)
9/9/81 (September 9, 2081)

Ron Gordon, a Redwood City, California high school teacher, created the first Square Root Day for September 9, 1981 (9/9/81). Gordon remains the holiday's publicist, sending news releases to world media outlets.

Gordon's daughter set up a Facebook group where people can share how they were celebrating the day.

One suggested way of celebrating the holiday is by eating square radishes (a type of vegetable), or other root vegetables cut into shapes with square cross sections  (thus creating a "square root").

The number of years between consecutive Square Root Days in a century are consecutive odd numbers: 3, 5, 7, 9, 11, 13, 15, 17.
This illustrates the fact that every odd number is the difference of two consecutive squares.
