Mastering Base, Project, Resource,
and Task Calendars
Bear with me because I won’t kid you: Mastering the four calendars in Project
2007 can be tricky. Understanding how calendars work in Project 2007,
however, is essential to mastering the software. Tasks are scheduled and resources
are assigned based on the calendar settings that you make. Thus, the costs
accumulated by resource work hours won’t be accurate if you don’t
understand your calendar settings from the get-go.
Because the use of the term “project” can get confusing as it refers to the
software, your project plan, and one of the calendar types (the Project
calendar), I need to explain the terminology I use in this chapter. I use Project 2007
when referring to the software itself, Project calendar when referring to the
calendar, and just plain project when talking about your project plan.
How calendars work
Here’s the lowdown on the role of each of the four calendars in Project 2007
(with more in the next section about how they interact with each other):
Base calendar: This is the calendar template that all other calendars are
built on top of. Three Base calendars are available: Standard, 24 Hours,
and Night Shift. (You read more about them shortly.)
Project calendar: This is the default calendar for scheduling. This is
where you choose which Base calendar template this particular project
Resource calendar: This combines the Base calendar settings with any
exceptions (nonworking times) that you set for a particular resource.
Task calendar: This is where you can set exceptions for a particular task.
When you create tasks and assign resources to work on them, Project 2007
has to base that work on a timing standard. For example, if you say that a
task should be completed in one workday, Project 2007 knows that a workday
means 8 hours (or 12 hours or whatever) because that’s how you set up a
standard workday in your Project calendar. Likewise, suppose that you assign
a resource to put in two weeks of work on a task in a company that uses a
standard five-day workweek. If that resource’s own calendar is set for a
standard four-day workweek, the two weeks of work put in by that resource defer
to the timing of the Resource calendar for a total of only eight workdays.
