<p><strong>Technical Note: Database Architecture</strong></p>
<p>This plugin integrates <code>webcalendar-core</code>, a framework-agnostic Composer library that provides all calendar business logic (events, recurrence, iCal, permissions) through 17 repository classes. These repositories require PDO and use exclusively parameterized prepared statements — no raw SQL concatenation. WordPress-specific data (users, options, capabilities) is accessed via <code>$wpdb</code> through the plugin’s Bridge layer (<code>WpUserRepository</code>, <code>WpConfigRepository</code>, etc.). See <code>src/Bridge/PdoFactory.php</code> for the connection factory.</p>

WP iCal Availability

This is a great little helper!

It is very easy to configure as there are not very much settings. It does one thing and this thing works great.

One note: The calendar blocks the whole day if there is just one entry on one day (however small it is).

If you know CSS you can style the calendar yourself a little bit more, because there are many classes used.

BUT it would be great if the calendar wouldn't be fixed in size. Although you can try to achieve a bigger calendar yourself with CSS.

And a complete shortcode documentation would be great. You don't need it, because there is a great GUI for it, but if you miss the button you are little bit lost.

As all those critics can be solved and are not about the core functionality the 5 stars are still valid.

Great plugin. Easy to configure. If you need more you can do it yourself with CSS and/or move to the premium version. 

Easy to configure

This calendar imports an iCal feed from an external website, like Airbnb, and shows the availability based on that feed.
