But many edible items have other numbers on packaging that aren't clearly defined.

One such extra value is found on egg cartons.

In the same area as the "best by" date, there's another number. That number indicates what day of the year the eggs were cartoned.

Consumers might find interest in figuring out how many days have passed since the eggs have been cartoned and how many days total an egg can sit before going bad. But don't forget: An egg could have been laid up to 30 days prior to being cartoned, according to Fresh Eggs Daily.
