License Laws

My boyfriend and I want to get married before we move into our new house. Our pastor is going to marry us but I know we have to get a marriage license first. My question is, Does going down to the courthouse and getting this license require more than one day? Or can it be done all in one day? Also what would we need to take? (as far as documentation?) Thanks!
I HAVE tried google. I could not find the specific answer I wanted. I thought asking someone who has been through this would be faster. You don’t sound like that person so be gone kid.
