Here’s a secret: the “sell-by” or “expiration” date is a guideline, not a law. Eggs can stay fresh for three to five weeks after you buy them if they’re kept cold. The date is mostly for the store’s inventory.
So if your egg is two days past its printed date, don’t panic. Use the float test first. The date is like a polite suggestion; your senses are the final judges. Remember that.
It’s like trusting a friend’s “best before” opinion over your own eyes. You’ve got the power to check. And that power is a sniff test and a bowl of water away.
