Its Sunday night. No one works on Sun nights in our group and they have had all weekend to spend time with family, get yard work done, schedule other events with friends, etc. Hell, we often have plans with friends on Sun afternoons, but we make sure we are done at a reasonable time so we can get home for gaming. If we did it on a week night, then the people with small kids really wouldn't see them all day because they would have to go straight from work to gaming. So, that wouldn't work. We have discussed switching it to Sat night or Sat day, but you have a much better chance of people canceling due to family events at those times.
