My T is in the office 3 days a week, pretty much 10-6. Her husband (who used to work in the same practice, before I started seeing her) is retired, so I think she decreased her days to just the 3.

My marriage counselor works 5 days a week, including a couple late evenings. He's called from the office at 9 p.m. before. He sees lots of teenagers (they're his specialty), so he shifts hours on some days to accommodate their school schedules.
