The free version of ICS Calendar requires you to create a shortcode with all of your configuration options typed in. Calendar Builder lets you configure one or more customized calendar displays with a user-friendly interface and generates a simple ID-based shortcode that you can drop in anywhere you would use the full ICS Calendar shortcode. Any changes you make to a saved calendar will automatically take effect on any pages where you’ve used that calendar’s shortcode.
Note that many inputs have a blue question mark icon. Hover over any of these icons for contextual help.
