How do you find old eggs?

Excuse me, I'm curious about a common household issue. How does one go about finding old eggs in their kitchen or pantry? Is there a specific method or technique that you recommend to ensure that I don't accidentally use an expired egg in my cooking? I've heard that there are some telltale signs to look for, but I'm not entirely sure what they are. Could you please elaborate on the best practices for identifying and disposing of old eggs?
