Set nonworking days in the project calendar

Calendars are the primary means by which you control when each task and resource can be scheduled for work in Project. In later chapters, you’ll work with other types of calendars; in this chapter, we focus on the project calendar.

The project calendar defines the general working and nonworking days and times for tasks for the entire plan. Project includes multiple calendars, called base calendars, and any one of those calendars can serve as the project calendar for a plan. As Figure 3-2 shows, you select the base calendar to be used as the project calendar in the Project Information dialog.

The Calendar list contains the three base calendars that are included with Project:

  • 24 Hours Has no nonworking time; all time is working time.

  • Night Shift Covers a night shift schedule of Monday night through Saturday morning, 11:00 PM to 8:00 AM (23:00 to 08:00), with a 1-hour break each day.

  • Standard The traditional working day and week, Monday through Friday from 8:00 AM to 5:00 PM (08:00 to 17:00), with a 1-hour break each day.

Only one of the base calendars serves as the project calendar; the Standard calendar is the default.

Think of the project calendar as your organization’s normal working days and hours. For example, this might be Monday through Friday, 8:00 AM through 5:00 PM (08:00 to 17:00), with a 1-hour lunch break each day. Your organization or specific resources might have exceptions to this normal working time, such as public holidays or vacation days (personal holidays). You’ll address resource vacations in Chapter 5, “Set up resources.”

You customize calendars as shown in Figure 3-3 in the Change Working Time dialog, which opens when you select the Change Working Time button on the Project tab in the Properties group.

Use this dialog to set normal working schedules and working time exceptions for individual resources or the entire plan. Other common examples of working time adjustments include the following:

  • Recurring holidays or other times off that follow a known pattern, such as weekly, monthly, or annually.

  • Variable working times per week—for example, to address seasonal changes in working times.

  • Unique working hours for a resource. You’ll adjust such settings in Chapter 5.
