Set weekends as Working Days in MS Project

How can I set weekends (Saturday and Sunday off) as working days in MS Project? I have gone to Project -> Change working hours and clicked on Working week. However, I cannot click on the “Details” button. Can someone please help me?

    Is your organization using either Project Online or Project Server with Microsoft Project?  If the answer is Yes, then you cannot create new calendars or edit existing calendard directly in Microsoft Project, which would explain why the Details button is grayed out.  You need to start the creating or editing process in Project Web App instead, which will then take you to the Change Working Time dialog in Microsoft Project, with the creation and editing features enabled.  Let us know and we will try to help you.
