What is Calendar Overlay in SharePoint Online?

Calendar overlay is a cool feature in SharePoint that lets you layer the contents of multiple calendars into a single easy-to-read, color-coded calendar view. Use it when you are managing more than one calendar in your SharePoint environment but want to create a consolidated view of all events across these calendars. For example, you may have a calendar for your Team and a calendar for your organization. You can combine them and view all events from both calendars (technically up to 10 calendars) in a single view.
