<p>CalDav Calendar Viewer fetches and displays events from any standard iCal (.ics) feed directly on your site using a simple shortcode. It supports multiple calendar feeds, each with its own URL and optional username/password for authenticated endpoints.</p>
<p><strong>Key Features:</strong></p>
<ul>
<li><strong>Multiple Calendar Feeds</strong> – Configure as many feeds as you need, each with a unique ID.</li>
<li><strong>iCal / RFC 5545 Support</strong> – Parses standard <code>.ics</code> calendar feeds including all-day events, times, locations, and descriptions.</li>
<li><strong>Recurring Events</strong> – Expands RRULE recurrences (DAILY, WEEKLY, MONTHLY, YEARLY) including BYDAY, BYMONTHDAY, INTERVAL, COUNT, UNTIL, and EXDATE.</li>
<li><strong>DURATION Support</strong> – Derives the end time from a <code>DURATION</code> property when <code>DTEND</code> is absent.</li>
<li><strong>Basic Authentication</strong> – Supply a username and password per feed for protected calendars.</li>
<li><strong>Encrypted Credentials</strong> – Passwords are stored using AES-256-CBC encryption in the database.</li>
<li><strong>Caching</strong> – Configurable cache lifetime reduces external HTTP requests (defaults to 1 hour).</li>
<li><strong>Cache Management</strong> – View the number of currently cached feed entries and clear them with one click from the admin settings page.</li>
<li><strong>Async Loading</strong> – Calendar events are fetched via AJAX so the containing page renders immediately.</li>
<li><strong>Label / Category Filtering</strong> – Filter events by iCal <code>CATEGORIES</code> labels using the <code>label</code> shortcode attribute.<br />
Accepts a comma-separated list; <strong>all</strong> plain labels must be present on an event for it to be shown.<br />
Prefix a label with <code>!</code> to exclude events that carry that category. Matching is case-insensitive.</li>
<li><strong>Clickable Events</strong> – Events that carry a <code>URL</code> property in the iCal feed are rendered as clickable links.</li>
<li><strong>7-Day Rolling Window</strong> – Automatically fetches and displays only the next 7 days of events.</li>
<li><strong>Responsive Event List</strong> – Clean event list layout that adapts to all screen sizes.</li>
<li><strong>Event Tooltips</strong> – Hover over an event to see its description.</li>
<li><strong>Description Prefix Filtering</strong> – Remove lines from event descriptions that start with configurable prefixes. Useful for hiding internal metadata added by calendar applications.</li>
</ul>
<h3>Configuration</h3>
<p>Navigate to <strong>Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> CalDav Calendar Viewer</strong> in the WordPress admin panel.</p>
<h4>Adding a Feed</h4>
<p>Click <strong>+ Add Feed</strong> and fill in:</p>
<ul>
<li><strong>Feed ID</strong> – A unique lowercase identifier (letters, numbers, hyphens, underscores) used in the shortcode.</li>
<li><strong>iCal Feed URL</strong> – The full URL to the <code>.ics</code> calendar feed.</li>
<li><strong>Username</strong> – Username for Basic Authentication. Leave blank for public feeds.</li>
<li><strong>Password</strong> – Password for Basic Authentication. Stored encrypted. Leave blank to keep the current value.</li>
</ul>
<p>You can configure multiple feeds — each gets its own ID.</p>
<h4>General Settings</h4>
<ul>
<li><strong>Cache Lifetime (seconds)</strong> – How long fetched calendar data is cached. Set to <code>0</code> to disable caching. Default: <code>3600</code> (1 hour).</li>
<li><strong>Description Line Prefixes to Remove</strong> – Newline-separated list of prefixes. Any line in an event’s description that starts with one of these prefixes is removed from the tooltip. Useful for hiding internal metadata added by calendar apps (e.g. <code>X-APPLE-</code>, <code>Reminder:</code>).</li>
</ul>
<h4>Cache Management</h4>
<p>The settings page shows how many calendar feeds are currently cached. Use the <strong>Clear Cache</strong> button to delete all cached responses and force fresh fetches on the next page load.</p>
<h3>Usage</h3>
<h4>Basic Shortcode</h4>
<pre><code>[caldcavi_calendar id="my-feed"]
</code></pre>
<h4>Shortcode Attributes</h4>
<ul>
<li><code>id</code> (required) – The feed ID configured in <strong>Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> CalDav Calendar Viewer</strong>.</li>
<li><code>label</code> (optional) – A comma-separated list of iCal <code>CATEGORIES</code> values to filter events by. <strong>All</strong> plain labels<br />
must be present on an event for it to be shown. Prefix a label with <code>!</code> to exclude events that carry that category.<br />
Matching is case-insensitive. Omit to show all events.</li>
</ul>
<h4>Examples</h4>
<pre><code>[caldcavi_calendar id="team-calendar"]

[caldcavi_calendar id="hr-events"]

[caldcavi_calendar id="team-calendar" label="Work"]

[caldcavi_calendar id="team-calendar" label="Work,Important"]

[caldcavi_calendar id="team-calendar" label="Work,!Cancelled"]

[caldcavi_calendar id="team-calendar" label="!Private"]
</code></pre>

ICS Calendar


I've never said this before, but this plugin actually has too many updates. It will have updates daily, and sometimes multiple updates in a single day. It's had 16 updates so far in March! It works well but please do like a month of development and then roll out a new version after testing. It's getting kind of crazy.


Too Many Updates

Excellent plugin and it just works. Was able to plug in an Outlook Office 365 ics file and it just works.

That's it, the plugin just works!

Thanks for sharing with us.

Just friggin works!


Lovely functionality and appearance straight out of the box.



I wanted to tweak the UX to have 2x calendars showing with interleaved events.. it just handles it perfectly.



Many thanks for an excellent plugin.


Unbelievably Useful
