calendar

 The calendar used in developing a project plan. This calendar identifies project work days, and can be altered so weekends, holidays, weather days, etc., are not included.

 The arrangement of normal working days, together with non-working days, such as holidays and vacations, as well as special workdays (overtime periods) used to determine dates on which project work will be completed.

 A project calendar lists time intervals in which activities or resources can or cannot be scheduled. A project usually has one default calendar for the normal workweek (Monday through Friday for example), but may have other calendars as well. Each calendar can be customized with its own holidays and extra work days. Resources and activities can be attached to any of the calendars that are defined.
