<p><a href="http://arshaw.com/fullcalendar/" title="jQuery Calendar Plugin" rel="nofollow ugc">FullCalendar</a> is a free open source jQuery plugin by Adam Arshaw which generates a stunning calendar populated with your events.</p>
<p>This plugin combines the power of FullCalendar 3.x and WordPress to present your posts or any other custom post type in a calendar format, which can be filtered by custom taxonomies such as categories and tags.</p>
<p><a href="http://demo.wp-events-plugin.com/calendar/" title="Events Manager Calendar Plugin" rel="nofollow ugc">Demo – See it in action</a></p>
<h4>Features</h4>
<ul>
<li>AJAX powered</li>
<li>Month/Week/Day views</li>
<li>Style your calendar with dozens of themes or create your own with the jQuery ThemeRoller</li>
<li>Filter by taxonomy, such as category, tag etc.</li>
<li>Supports custom post types and custom taxonomies</li>
<li>Popout/Tooltip post summaries and thumbnails when you hover over your calendar items.</li>
<li>Integrates seamlessly with <a href="https://wordpress.org/extend/plugins/events-manager/" rel="ugc">Events Manager</a></li>
<li>Various hooks and filters for added flexibility for developers</li>
</ul>
<h4>Credits</h4>
<ul>
<li>Big thank you to Michael Lynn who generously gave us this plugin namespace after deciding not to go through with his implementation. One less confusing name on the plugin repo!</li>
<li>This plugin was originally created for <a href="https://wordpress.org/extend/plugins/events-manager/" rel="ugc">Events Manager Pro</a>, which has been moved over here so it can be used by the community for other post types. Support and maintenance is sponsored by proceeds from this premium plugin, so if you’re in need of a good Events plugin, give it a try!</li>
</ul>
<h4>Roadmap</h4>
<p>Here’s a rough roadmap of where we’re heading, and will be ammended as time permits</p>
<ul>
<li>Move to FullCalendar 5.x library</li>
<li>Remove jQuery dependency (due to 5.x transition and select boxes)</li>
<li>Add Gutenberg blocks</li>
<li>Add more native FullCalendar options to the settings page</li>
<li>Add formats for custom post types (currently only possible with Events Manager)</li>
<li>Colors for other taxonomies (currently only possible with Events Manager)</li>
<li>Multiple post types on one calendar</li>
</ul>
