The P6 application supports three types of calendars:
- Global: Global calendars can be defined and applied to all projects and resources in the database.
- Project: Separate project calendars can be defined and applied to projects through activity assignments.
- Resource: Resource calendars can be defined and applied to each individual resource.
Begin by defining one or more global calendars and then link any project or resource calendars to them. Changes to a global calendar apply to all project and resource calendars linked to it.
Assign global or resource calendars to resources, and global or project calendars to activities. You can establish an unlimited number of calendars to accommodate different work patterns. For example, if some activities require a five day workweek, while others are performed part-time (such as Monday, Wednesday, and Friday), you can create different calendars and assign them to the activities and resources in your projects.
An activity’s Activity Type field value determines whether the activity uses the calendar of an assigned resource or its project calendar.
