What does the expiration date on milk cartons mean?
I have different experiences with the date:
- There is still about a week before the expiration date but the milk has gone bad
- It is 1-2 days after the expiration date but the milk doesn't smell or taste bad
In both case, the milk was kept in the fridge.

There is a lot of variability in how fast milk will go bad.
All of these influence how long milk stays good. The big date on the top is used by grocers to determine when it can't be sold. If you look closer there will be text to the effect of, "Use within 7 days after opening". This isn't a guarantee. Leaving the carton out while you cook will allow it to go bad faster, as will keeping it in the door. Also if your fridge is too warm for some reason, things will spoil faster.
