It demonstrates the ability to render the calendar inside your articles/components/whatever. This article is included inside a table. I have place on the cell on the left a div with ID "calendar_custom", and changed the alternative div text (on the back-end) to the same ID.

To demonstrate the events and the method available on the new module, I have created a custom HTML module and added the text below on it.

The onclick event uses the method to add events to a date.

The next two functions are implementations of the event functions. The one returns an alert when the month changes, and the other when a date is clicked.

To check the code, you can use a tool like firebug on the module on the right.
