Church gigs - typically at the place at 6:30 AM, out at 12:30 PM. Rehearsal - 45 minutes to an hour. Run through - 25 to 30 minutes. Each service (usually 2) has 25-30 minutes of music. The rest is hangout time. We also have midweek rehearsals - typically a couple hours from load in to out the door. It's a different vibe than a bar gig in almost every way.
We’re pretty close to your Sunday schedule except we have 3 services. Our pre-service run through starts at 7:00 and we are done at 12:45. We have a rehearsal on Monday’s that lasts and hour 20 minutes or less. We use IEMs and keys and drums are provided so there is no real load in time.
As for commercial gigs it depends. Mostly it’s (2) 1 hour sets with 20 minutes in between. Pretty much we play for older people and they are about ready for bed by the time we are done with them...lol!!!
