<p>The operations calendar ( [Operations</a> Calendar at the University of Virginia](<a href=“http://www.virginia.edu/registrar/OperationsCalendar/operations2.html]Operations”>http://www.virginia.edu/registrar/OperationsCalendar/operations2.html) ) doesn’t say, but I remember it being 7am (when ISIS opened) my first year. Since there is maintenance 5-7am for SIS I would assume it to be 7am.</p>
