Click “Add” at the bottom of the window. The new data source will now appear in the list.

Create new SharePoint data source

if you add a new source, choose a SharePoint list from the available list and fill in the required fields: name, site URL, data source time zone, fields for event title, start date, and end date.

For a calendar to display the time correctly, ensure that Datasource Timezone matches the time zone in SharePoint settings.

To check if they match, go to your SharePoint site, click on the gear in the upper right corner, then find “Site settings” (or “Site contents” -> “Site settings”) => “Regional settings,” and make sure the time zones match.
