ELI5: Explain Like I'm 5

Expiration date

Alright kiddo, an expiration date is a special date that tells you when something like food or medicine is not good anymore.

Think about how sometimes you see things in the fridge that look and smell funny, and sometimes we feel sick after we eat them. That's because they're expired and not safe to eat anymore.

The expiration date is like a safety check, so we know when it's time to throw something out because it's not good for us anymore. It's an important way to make sure we don't accidentally make ourselves sick by eating or using things that have gone bad.
