You can modify the three Base calendar templates and create new templates
from them. See the section “Creating a Custom Calendar Template,” later in
How one calendar relates to another
All calendars in your project are controlled, by default, by the Project
calendar setting. Here’s the tricky part, though: When you change a Task or
Resource calendar (this type of change is referred to as an exception ), you
have to understand which setting takes precedence.
Here’s how this precedence thing works:
With no other settings made, the Base calendar template you select for
the Project calendar when you first create the project controls the
working times and days of all tasks and resources.
If you make changes in the working hours for a resource, those settings
take precedence over the Project calendar for that resource when you
assign it to a task. Likewise, if you assign a different Base calendar for
a task, that calendar takes precedence over the Project calendar for
If you apply one calendar to a resource and a different calendar to a task
that the resource is assigned to, Project 2007 uses only common hours to
schedule the resource. For example, if the Task calendar allows work from
8 a.m.–5 p.m. and the Resource calendar allows work from 6 a.m.–2 p.m.,
the resource works from 8 a.m.–2 p.m., which is the only period the
calendars have in common.
You can set a task to ignore Resource calendar settings by opening the
Task Information dialog box (double-click the task name in Gantt Chart
view) and selecting the Scheduling Ignores Resource Calendars check
box on the Advanced tab. (This setting isn’t available if the Task
calendar is set to None.) You might make this setting if you know that all
resources are required to be involved in a task (such as a quarterly
company meeting), regardless of their usual work hours.
Calendar Options and Working Times
Just when you thought that you were out of the woods, I’ll throw two more
timing elements at you — calendar options and working times.
