ICS Calendar Pro supports all of the features of the free version, plus eight additional views, extra options in the four core views, an intuitive Calendar Builder interface, font and color tools in the Customizer, and more!
ICS Calendar Pro also includes ICS Events, a full-fledged calendar management system. Create and manage events directly in WordPress, and integrate them seamlessly with ICS Calendar.

*Sadly nothing is truly “forever,” but in this case, it means you’ll get updates and support for as long as we are actively maintaining ICS Calendar Pro.
This plugin includes the PHP ICS Parser library by Jonathan Goode, John Grogg and Martin Thoma (MIT license). ICS Calendar Pro also includes Plugin Update Checker, FullCalendar, Masonry, and an appropriately licensed, embedded version of Advanced Custom Fields Pro, configured to function solely on ICS Calendar admin screens. If ACF Pro is already installed on your site, your installed version is used, to avoid any conflict.
