Given that this is the second reply of its class, sounds like some of y'all have sketchier local councils than I do.
Perhaps this disenfranchisement is more of a regional issue.
I don't think it's necessarily sketchy. Any time you pick will be better for some people than others, and it's possible that earlier is more convenient for the groups who demonstrably want to attend their meetings. For example, if the people who come to your meetings are primarily stay-at-home spouses and retirees, you'd probably be inclined to pick a time when they're most comfortable.
