9/16/25 is one of the rarest days as firstly the month and day 9 and 16 add up to 25, the year but that isn’t special, right? There are 12 of these in a year, have been since 2013, and will continue to be until 2031 as there’s no 2/30/32. What’s really special is 9, the month is 3^2, 16, the day is 4^2, and 25 the year is 5^2. That makes consective 3, 4, 5. (Coincidentially, next is 6 7 the biggest meme of August-September 2025 if you’re reading this in like 2029 or something) Even more special, 3^2+4^2=5^2 is the Pythagorean Thoerem, as if the sides of a right trangle are 9 and 16 the hypotenuse is 25, the bigger version of the 3 4 5 triangle. The next time a consecutive Pythagorean Thoerem date will happen will be on 4 January 2101, as 2036 or any year doesn’t have a 16th month so no 16/25/36. Also, 2025: 20+25 is 45 and 45^2=2025. If you write the date with both two and four digit year methods (9/16/25 and 9/16/2025) you’ll get all 3 numbers squared. The next time this’ll happen will be 9/16/3025, with 30+25=55 and 55^2=3025.

Yes I might have came from OkCron but whatever today’s a special day.
