Army reserve weekend hours

So Im waiting for my packet to clear but I passed the medical. Im curious if anyone knows what the hours are like in the army reserves? Im in Miami and the recruiter told me I could be at the VA and I would work a regular shift and go home on saturdays and sundays. Im curious what everyones hours are like when they do their 1 weekend a month with the reserves. Do you guys get out on time? The hospital I work at the shift is 7-7:23 but get out at like 8-8:30 so I was wonderin if its the same at the VA or other reserve locations. Also, are the 2 days a month flexible or is it a set date and it has to be weekend? Does anyone think I would be able to work my 2 days a month on a mon-fri basis? Thanks
