Your website can contain multiple calendars (or just one calendar). Once you have selected to create a page with the page type of calendar, you will see the following items in the menu:
Modify Page Header
Modify Page Footer
The Modify Page Header, Modify Page Footer, and Modify Links work the same as every other page within the system, so we won't be talking about how that works on this page. What are unique to only the calendar pages are the Configure Calendar and Modify Events.
