The “All-in-One Event Calendar” by Time.ly works great, but uses dynamic javascript. 
This plugin creates a static version of the javascript that can be cached by 
the browser.
I have tested this plugin with versions 2.1.9 and 2.2.0 of the event calendar plugin. 
It may work with future releases, but use it at your own risk.
This plugin only uses the static javascript on the frontend. If a user is 
logged in, the original dynamic script will be used. As far as I can tell 
caching the javascript does not interfere with the plugin’s functionality, but 
there may be features of the event calendar that do not work with this plugin.
