How to search according to the hrs. of opening, not according to where you live, etc?

Let’s say you need to go to the clinic, store or whatever else that has the longest opening hours, and you’re willing to go many area codes worth since the ones in your area (home work vacation location etc.) open too late or close too early. The search terms “longest opening hours”, “earliest opening hours” or “latest opening hours” only recognized as just the opening hours part. A lot of websites sites ask you to enter your postal code, before you can do anything period. So you have to enter many postal codes, one by one, very time consuming, and that’s if you already know by heart all those postal codes and you don’t need to search.
