Today's event is on a SQUARE ROOT DAY, 05/05/2025, as both the month (5) and the day (5) are the square root of the last two digits of the year (25). The first SQUARE ROOT DAY was created by Ron Gordon, a high school teacher, on 09/09/1981. It is an unofficial holiday where people often celebrate by eating roots. The last SQUARE ROOT DAYS were 03/03/2009 and 04/04/2016, and the next one wiil be 06/06/2036. Only 9 dates every century qualify to be a SQUARE ROOT DAY.
In addition, Geocaching's 25 Years in 2025 is extra special because the year 2025 is a PERFECT SQUARE YEAR. A PERFECT SQUARE YEAR is the product of a number multiplied by itself as in 45 x 45 = 2025. This phenomenon has not happened for decades. The last time it occurred was in 1936 = 44 x 44 when President Franklin D. Roosevelt was in office. Previously was 43 x 43 = 1849.
Geo-event Time is 6:45 to 7:15 a.m. and Location is King Station Amtrak Piazza.
