Line 42: Line 44:
 If the ultimate due date falls on a closure day, the Circulations dialog then counts backwards to find the last safe day on which the Item is due for return. This is done so that the due date does not fall after an absolute limitation such as the library, Reader or Item no longer being available. It is possible therefore, that the calculation results in a due date that is the same as the base start date. If this situation occurs, so that the duration is now 0 days, the circulation is no longer permitted. If the ultimate due date falls on a closure day, the Circulations dialog then counts backwards to find the last safe day on which the Item is due for return.
