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.
Swede here. Those labels are from the producer. It’s easier to just use the same bags and then add the expiration date on a separate labels than to print the expiration date on the bags themselves.
That way if you make same same bread on the same date but one batch gets frozen and the other gets sent out fresh you just use the same bags but they get different labels with different exparation dates depending if they are frozen or fresh.
