You can use the Event Calendar Group part to create a top-level calendar that receives events from smaller sub-calendars. For example, the academic departments, athletic department, and alumni association at your school each maintain a calendar on your website. Your website also has a main calendar that includes events for all areas of the school. In this scenario, the departments and alumni association create their own calendars with the Event Calendar part. You can then create an Event Calendar group for the main school calendar and assign the department and alumni calendars as sub-calendars of that group. For more information about the Event Calendar part, see Event Calendar.
