The answer is no, the entered or calculate task duration does not include non-working days. For example, if you have a duration of 10 days, and there is a long weekend in the middle. The actual number of calendars days could be 15 days because of a potential 5 non-working days.

We can see in the example below that a task with 5 days duration that starts on a Tuesday and ends Monday crosses over weekend, will actually take an estimated 7 calendar days to complete.


Microsoft Project has an elapsed duration data type. It is a task duration in calendar day. If you transfer Microsoft Project schedule to RiskyProject, elapsed duration will be converted to duration without non working days based on start and finish times of tasks.
