In our team, we work as much as we possibly can. That means, at any time where we have access to the shop and our allowed to work, except in the middle of the night (because of sleep + adult supervision is usually a teacher that doesn't actually care about the team).
We're not allowed to work during school, which ends at 4PM, and we leave at 10PM usually on weekdays (sometimes later).
On Fridays we're only allowed to work to 4PM (because of sabbath), and start at 9am.
On saturdays we work 10AM to 10PM (we're not supposed to be allowed but we found a way around it that involves parents).

So all and all, we work 6*5+7+12=49 hours a week.
