Currently, I have two games, one on Saturday and the other on Sunday. Both run from roughly 6pm to 11pm.
This however is somewhat new to me. When I was in college, Thursday was my night of choice. At one point I even had four games a week from Mon-Thurs. Unfortunately, much of my gaming group, myself included, has graduated and joined the workforce, which has moved our games to the weekends.
