1. What are your business hours?
2. When are you open?

We can ask a clerk and a librarian the second question, but we can't ask a librarian the first question, can we?

"Business hours" are for organisations carrying on a business.
For libraries, you can use "opening hours". In fact, you can use this term for businesses as well.
