Regarding Study Room reservations, how is "72 hours before" calculated?
Answer
Library study rooms are made available to book 3 days in advance of the booking time. This means that you may need to go online to the Library Rooms calendar site on Saturday or Sunday to reserve for Monday. Note: the library building itself may be closed on a given weekend, but you can usually log in to reserve a room for another day. The start time of a reservation needs to be 72 hours or less in the future from the time at which the booking is created (i.e. whole days aren't opened up for booking all at once: it's a rolling 72 hour window for allowable booking start-times).
