Each project can have its own calendar. The project calendar that you specify can be used to override the Company calendar, or you can use the Company calendar for the project. If there is no project calendar, or a project calendar is not in use, the Company-level Standard Calendar marked as the default calendar is the calendar that is used by the project. Project calendars can be based on Standard Calendars created at the Company level, or Custom Calendars created for the specific project. The project calendar you create applies only to the project for which you create that calendar. The calendar selected affects project durations and due dates.
For example, companies can have multiple projects in different countries that have different working and non-working days. These working and non-working days must be considered when determining such time-driven factors as business process workflow due dates and activity dates in schedule sheets.
Note: Unless otherwise specified, the default calendar for a project is the Company calendar that is marked as default at the Company level.
To create a project calendar
| 1 | Open the Calendar tab of the Project or Template window. The calendar you create in this tab is known as the Project/Shell Calendar. |
| 2 | You can select a Company-level Standard Calendar, or use a Custom Calendar for your project. The calendar that you select displays in the Calendar tab. |
| • | To use a Standard Calendar as the project calendar, click the Standard Calendar radio button and select a calendar from the drop-down menu. |
| • | To use a Custom Calendar as the project calendar, click the Custom Calendar radio button and click Copy. You can copy a previously-created Standard Calendar and use it as the project calendar. |
| 3 | You can modify the displayed calendar. You can specify the working and non-working days for the calendar. Browse to the month and year using the pull-down menus at the top of the calendar. Saturdays and Sundays are set as non-working days by default. Do one of the following: |
| • | To set a particular date as a non-working day (for example, a holiday), click the date on the calendar and select Non Working. The date will appear greyed out, and will not be used in date calculations. |
| • | To set a non-working day as a working day, click a greyed cell and select Working. |
| • | To set a particular day of the week (for example, every Saturday) as a non-working day, click the day at the top of the calendar (for example “Sat”), then click Non Working. All Saturdays in the calendar will be changed to non-working days (grey). |
| • | To set a particular day of the week as a working day, click the day at the top of the calendar, then click Working. |
| • | If you only want to set the day of the week in a particular month as working or non-working days, select each day individually and click Working or Non Working. |
Note: If you have marked the day of the week as a non-working day throughout the calendar by selecting the day at the top of the calendar (for example "Sat"), then you will not be able to mark individual days (that is, individual Saturdays in this example) as working days. To be able to include both working and non-working instances of a day of the week on the calendar, you must select them individually.
| 4 | Click OK. When you click OK, the calendar displayed in the Calendar tab is the project calendar. |
