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.
I mean, I’m sure just like “the other site” there are a bunch of folks just attempting to be funny. Some folks are really serious about date standards though, woof.
Just enjoy your timeless bagels and try not to go full Everything Bagel on us.
