The Default Calendar
Each time you create a new calendar file, Open Plan automatically creates a default calendar that defines a Monday-through-Friday workweek with no holidays.
Each work day has 8 working hours — 8:00 A.M. to 4:00 P.M.. This default calendar serves as the model for all new calendars added to the file.
In addition to using the default calendar as a model for subsequent calendars, Open Plan applies the default calendar to all activities and to resources that have not been assigned specific calendars.
You can modify the contents of a default calendar at any time. Although changing a default calendar has no effect on existing calendars in the file, any calendars you add thereafter will be based on the new defaults. Thus, you can customize a default calendar using the most commonly used work calendar (which might include, for example, a list of standard corporate holidays) and then set up subsequent calendars on an exception basis.
