Found this on the universityparent website. It’s old, but probably still holds true.
Move-In Day for first year students is Thursday, August 21, between 9 a.m. and 5 p.m. You may arrive to help with move in anytime during those hours. If necessary, family members should make arrangements now for overnight accommodations. Activities for students begin on Move-in Day at 5 p.m., and family members should plan their good-byes based on that schedule.
