Simple Calendar is an extensible plugin that supports add-ons, which are simply WordPress plugins themselves that add features and functionalities to the core plugin. See our complete list of add-ons.
When installing an add-on plugin you must ensure that Simple Calendar is already installed and activated.
There are both free and premium add-ons available. Free add-ons are available on in the WordPress.org plugin directory and can be installed similar to Simple Calendar itself.
Premium add-ons such as Google Calendar Pro are also available. Click here for premium add-on installation instructions.
