I think we all struggle equally with this and there's no perfect answer. If yours is a pretty typical community, more often than not both parents will work outside the home. Certainly people work a variety of shifts and jobs, but that usually means the majority of people are available in the evenings. Then you start looking at it day by day.
Monday - some avoid Monday because it's right after the weekend and people forget. Others like Monday because it may be less scheduled than other worknights.
Tuesday / Thursday - these seem to be two of the most popular for groups I'm in, but then we may get into seasons where one or both are heavy sports night (especially Thursday).
Wednesday - some avoid this because it's still considered a "church night" for many families. Others don't see it as an issue.
There are groups who hold their meetings during the day. Maybe someone else can speak about those and how well they worked. I've never had a group even consider it because the majority of our community would not be available.
There is no perfect day/time. You'll just have to work through the issues and pick the best for your group.
But I can tell you this - make the meetings a reasonable length (shorter is better) and full of good information. No one is eager to go to a meeting that's seen as a waste of time.
