Our schedule is:

M-F: 6-9pm
Sat: 1-6pm (this is approximate, and can change year-to-year)

So, about 20 hours (I voted for <30, since we are on the edge). We never really work extra, except that we often work until midnight the last night before bag. About the only exception is a few kids have worked on something-or-other during shop class a few times a few years.

I'm frankly surprised by those who can find 50 hours in a week; when are you doing this, all day?

As far as I know, the school doesn't have any particular restrictions on when we can be there. We even usually show up on snow days when the weather is actually acceptable. This year, for example, the HS had a faintly ridiculous number of snow days, but the only one that I recall that canceled our meeting also led to the university being closed, and I couldn't get out my driveway to get to the HS.
