Add Calendars

Calendars define which days count as working days for the purpose of calculating Task dates and durations. Because they're Project-level objects, more than one Calendar can exist within the same Project, and different Tasks or Teams can be assigned different Calendars — so a six-day crew and a five-day trade can sit in the same Plan without their date calculations interfering with each other. 

Each Task resolves its working days through a hierarchy (its own Calendar, then its Team's, then a Project default, then a built-in fallback), which means Calendars give teams a consistent, structured way to handle mixed working weeks and holidays without manually adjusting individual Task dates.

1. Open the Control Center
    
2. Click on the Calendars section
    
3. Click on Add Calendar
    
4. Type a name for the new Calendar
    
5. Program the working days so they are yellow and non-working days are black by clicking on them as needed
    
6. Add workday overrides (holidays) by typing the date or clicking on the calendar icon to choose the date
    
7. Click the blue plus button to add the override
    
8. Add a reason/title of the override
   • You can always return to this screen to either turn off the override or delete it
      
9. Follow steps 6-8 for all known overrides that span the length of the Plan
    
10. Click on the three-dot icon on the top right corner of the window if you want to make this the default calendar
     
11. Close the window using the X on the top right corner

Repeat these steps for the different calendar configurations your Teams plan to use. Click on the pencil icon on the right side of each listed Calendar to edit it.
