It actually depends on which residence you move into, as there are two move-in days. Last year the schedule was different from the three previous years, so I'm not sure which residences are going to move in which days this year.
The first day of move-in this year is the last day of August. So, I would go with the assumption that you would need that day off. It's a Saturday, anyways...so if you'd be working full-time hours you wouldn't be working anyways.
