In this video we take a look at several advanced configuration options when working with calendars. We start off by talking about the various pager options available and how that works with AJAX, and then we explain how you can keep track of the current date that someone is viewing the calendar in as they move through the various displays. We wrap up by covering three methods for working with caching to improve your site's performance, as calendars can be intensive, depending on the site. We'll discuss caching with the Entity cache module, using the Date API date caching, and then review using views caching.
