You can modify a standard calendar if you have Modify permission. You can delete a standard calendar if you have Create permission. If you use a calendar in a shell, project, schedule sheets, or schedule sheet activities, and you are asked to replace the calendar, you can delete the existing calendar and replace it with a new one. You can also specify a default standard calendar if you have Create permission. Unless otherwise specified, the default calendar for a project or shell is the company calendar that is designated as the default calendar.
Note: The calendar selected affects project or shell durations and due dates.
To modify a calendar at company level (Classic View)
- Go to the Company Workspace tab and switch to Admin mode.
- Click Standards & Libraries > Calendars in the left Navigator. The Calendars log window opens.
- Click the company calendar to select and click Open. The Calendar Properties window opens.
- Modify the calendar name and change the optional description as needed.
- Modify the working and non-working days that are specific to the new calendar you are creating. Select the calendar day and click the Working or Non Working options as needed.
- To change a particular date from a working to a non-working day, click the date cell to highlight and click Non Working. You can select multiple dates. This change impacts the months individually and does not impact the rest of the calendar or subsequent years.
- To change Saturdays and Sundays from non- working days to working days, click the day cell for example "Sat," to highlight and click Working. This will make all Saturdays, or Sundays, of the calendar as working days, including subsequent years. In this scenario, you can select individual dates under Saturdays or Sundays and mark them as non-working dates.
