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.
Spoken and written don’t need to use the same format. Time also isn’t spoken using the written format hhmmss.
So then we agree there is more than one correct date format.
