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.
Everyone’s getting the dates wrong, it’s clearly the 23rd month of 2902 👍
That can’t be it either since 2902 isn’t a leap year so it only has about a dozen months
Lousy Smarch weather…
