Eggs are good for about 5 weeks in the refrigerator once you buy them.
As long as the eggs remain refrigerated the eggs can last up to 5 weeks in the refrigerator even when the expiration date has passed.
The eggs are not always bad just because they have expired as long as they are refrigerated they will last 5 weeks which is a little over a month.
You can also freeze eggs and they will last up to a year in the freezer but the shells will crack but that's not usually a problem when you get ready to cook the eggs.
Just crack the egg further and remove the egg shell and put the frozen egg into the pan to thaw for 10 minutes or so and then cook the eggs.
