I am using a 5 working days & 8 hours standard calendar. My task is 30 days . I have selected a start date on Monday and end date on Friday (30th work day) but the durationn reflects as 40 days instead of 30 days? How can I ensure that the duration reflects the correct work days for the task?
Hmmm - a very quick google search gave this: https://blog.epmainc.com/more-you-want-know-about-duration-everything-you-need-know/:
When you enter a Duration value for a task in Microsoft Project, the software always calculates the schedule of the task in working days. ... For example, an elapsed Duration value of 20 days means 20 calendar days, including weekends and company holidays
So in practice, the 10 additional days are weekends.
