noun form of phrase means "after hours"

Question

I think the phrase after hours is adverb, so it cannot be used in the sentence below as it needs a noun.

What's the suitable noun?

The closing time of childcare centers is usually earlier than after hours of companies.

Answer 1

There isn't really anything convenient. But even if there were, this is a very roundabout way of saying

Childcare centers usually close earlier than (most) companies.

I'm guessing that what you mean is

Childcare centers usually close before parents can leave work.
