Calendars
Calendars, also known as schedules, define the standard working and nonworking time for projects and resources to which they're assigned. Working times are the days and total hours in a calendar during which work can occur.
Nonworking times in a calendar are days and total hours for which work isn't scheduled, such as weekends and holidays.
Project application administrators can create calendars from the Manage Project Schedules page. Keep in mind that projects and resources can use only calendars with the Elapsed schedule type with one workday pattern of 7 days and one project shift.
A calendar consists of the following components:
-
Shifts: A shift is a period of time that can be defined by a start and end time, or duration. Only one shift per day is supported in Project Execution Management or Project Resource Management.
-
Workday Patterns: A workday pattern is a collection of one or more shifts for a specific number of days. A pattern repeats itself for a date range to define the complete schedule.
-
Schedule Exceptions: A schedule exception is a deviation from the schedule. The two types of exceptions are off period exceptions and work period exceptions. Off period exceptions convert working days to nonworking days. And, work period exceptions convert nonworking days to working days. Also, keep in mind that only full day exceptions are supported.
Assign Calendars to Projects
A project manager can assign a calendar to a project during project creation or when managing the project plan. The working days and total hours in the calendar are used to schedule the project plan. Project managers can also create events on the project calendar such as PTO, training, and team building activities.
Assign Calendars to Resources
Project application administrators can select a resource calendar when creating or editing a project enterprise resource. The working days and total working hours in a resource calendar are used to determine resource availability.
The Project Resources work area uses the resource calendar to determine a resource's available hours for a project. The Update Resource Utilization Data process calculates the resource's projected utilization with the available hours.
Set up Default Calendar Assignments
Project application administrators can select a default project calendar and resource calendar on the Define Project Management Implementation Options page. The default project calendar is automatically assigned to new projects, and the default resource calendar is automatically assigned to new project enterprise labor resources.
If you don't set up a default project or resource calendar, a predefined calendar with 8 hours per day, 5 days per week will be assigned. In the predefined calendar, working days are from Monday to Friday.
