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.
You’re so close. Even in European date formats, the 29th of February doesn’t exist.
I understand that… I’m just talking about the users fixating on the date format. Look at all the examples in the comments.
It exists in leap years. 2023, however, wasn’t a leap year.
