1. 'What are your operating hours' and 'What are your buisness hours' are two phrases that have the same meaning. This tells the listener that you would like for them to list the time that they both open and close.
Ex: A) "Hello I would like to know your business hours?"
B) "Sure, we are open from 8 A.M. to 9 P.M. everyday"

How late/how early are you open?
What are the store's operating hours?
If you's like to now all of their hours in general, then you might want to ask about the store's "operating hours" but if you'd like to come at a specific time then you ask a simple " how late are you open?" if you're running late or "how early are you open?" if you plan to show up early the next day.
Let's say you've been procrastinating to go to this store. This is my usual experience.
Me: Hello good evening! I'm just calling to check how late your store will be open tonight?
Store: Hi, we're closing in 30 minutes.
Me: Ok, thank you very much! (speed!)
You can use the same type of question with "how early"
