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.
These numbers are put on by grocery clerks with a price-gun. All they did was add on however many days the product is supposed to last after it got put on the shelf. So it’s really just some grocery worker not worrying about a date not existing. I woulda done the same thing if I was stocking these tbh.
I schedule all my meetings for March 31st.
What? This makes so little sense I don’t even know how to proceed. It’s an expiration date.
