I originally posted this on the other site back when I took the picture, and it resulted in a lot of confused comments, especially from Americans, eventually getting removed by overzealous mods. Either way, I promise you that this date does not exist, and has never existed.
It’s just the EU date style.
I find my brain reads dates the US way first and then immediately rereads the EU way after, when that doesn’t make sense. It’s pretty automatic.
Not even tangentially related… but I replaced the dumb American (and I know UK as well) 3 fingers gesture with the German 3 when I learned of it as a teenager. It’s so much more efficient and reasonable compared to stretching our fingers out unnaturally…
Isn’t it basically the rest of the world style? like metric?
