The Calendar Aggregator for SharePoint allows users to combine data from multiple calendars into a single calendar. For example, an organizations SharePoint Corporate calendar located on their home page can contain all the events or appointments from calendars located in subsites that are relevant to all users. The Calendar Aggregator Web Part is fully customizable. The user can select the sites and specific calendars where the event data is to be aggregated from and the number of records that will appear per page.
The Calendar Aggregator will also allow you to specify the event fields (metadata) you would like to be displayed and modify the appearance of the list.
The Calendar Aggregator Web Part comes with a robust installer to allow it to be easily deployed within any SharePoint environment.
