What time does your church service end?

I am having a Sunday wedding, and trying to get a day-of rough draft timeline going. I have my photographer from 12pm-10pm, and Im waiting for snail mail from my venue with the info about when we can start set up and such. Then I realized while we might not be casual attendees at church, that doesn't mean some of our guests should skip a service that might speak to them, you know? Scheduling around church end times and post church things like brunch or grocery shopping sounds like a good start.
