Question: I have some eggs in the refrigerator that I’d like to use, but the date on the carton was a week ago. Are they still safe to eat?
Answer: Yes, your eggs should be fine, provided you’ve been storing them properly.
As the Washington-based Egg Safety Center notes, the dates you see on egg cartons are not food safety dates. They are most commonly used as a guide for stores to know how long they can sell the eggs.
Raw eggs will maintain their best quality for about 3 to 5 weeks after the date you bought them and took them home, assuming continuous refrigeration.
During that home storage time, the "sell-by" or “expiration” date on the carton will usually come and go. But your eggs will still be perfectly safe to use, provided they’re not cracked or otherwise damaged.
If you want to store your eggs for longer than five weeks, your best bet is to freeze them, following the instructions outlined here.
