Choose a specific calendar for a site page
When you have added Calendar Overlay Pro to a SharePoint site page, you can switch between the available calendars using the calendar selector. Sometimes, however, you may need to choose a single calendar to show on the page. In this case, switch to edit mode and click the “Edit web part” icon.
Edit calendar web part
In the web part settings, choose the default calendar you wish to show and uncheck the “Show calendar selector” option. Republish the page.
Uncheck the calendar selector
Now only the chosen calendar will appear on this page.
