The Calendar feature is automatically activated once a feature is activated that supports the Calendar function. The use of the Calendar may be updated in future versions to allow for a more versatile and broader use of its functionality, but for now, it supports the following features:
The Calendar can appear on your website anywhere using a Shortcode pasted into a Shortcode Block. There are a few ways that it can be displayed, and the design can be changed using the Settings in the WP Admin > Settings > Calendar page.
The Calendar supports the iCal format, so you can subscribe to the Calendar and have it appear in any Calendar app that supports the iCal format (including Microsoft Outlook and Gmail). If the Subscription option is enabled, there will be a button below the Calendar labelled Subscribe. Once clicked, a note will popup on the visitors screen to say that the Calendar URL has been copied successfully, this process copies the Calendar Feed URL to the clipboard. This URL can then be pasted into the desired Calendar app as an Internet Calendar, which will then sync with the Calendar on your website and update regularly.
