My friend @kfury points out that 9/16/25 is closely related to a 3-4-5 triangle and says it's Pythagoras Day.

@evan @kfury Pythagoras would never tolerate a MDY year format.

@johnefrancis @kfury fair! In Pythagoras 's time, it was typical to describe dates with as "Nth of Month" or "N days before the end of Month". Month names were regional. Year numbers were usually based on the year of rulers or leaders in the city. So, he'd know a date format more like: +/- day, Month name, year of rule, ruler or leader name.

@johnefrancis @kfury it works fine in 16/9/25 format too, btw. Doesn't depend on order!

@evan @kfury I suppose a 4-3-5 triangle is equivalent to a 3-4-5. But nobody can market a 4-3-5 triangle, you'll get laughed out of a half-finished monument with that!
