FullCalendar in WordPress is not working

You page is generating two errors: Uncaught TypeError: undefined is not a function.

This is likely due to the fact that WordPress sets jQuery to NoConflict mode. Your script is using the $ shortcut and is failing.

Modify your script accordingly, either replacing the shortcut or wrapping the jQuery.
