<blockquote>
<p>[!WARNING]<br />
  At this time, only <strong>one calendar per page or post</strong> is supported.</p>
</blockquote>
<p>On the long run it’s planned to have a Rest API to allow the calendar being rendered with more modern frontend tools than the current, outdated, but nice old Bootstrap 3 stuff.</p>
<h3>Shortcodes</h3>
<h4>Calendar Views</h4>
<pre><code>[osec]                       // Default view per settings
[osec view="monthly"]
[osec view="weekly"]
[osec view="agenda"]
[osec view="daily"]
</code></pre>
<h4>Filtering</h4>
<p><strong>By category</strong></p>
<pre><code>[osec cat_name="Holidays"]
[osec cat_name="Lunar Cycles,zodia-date-ranges"]
[osec cat_id="1"]
[osec cat_id="1,2"]
</code></pre>

<pre><code>[osec tag_name="tips-and-tricks"]
[osec tag_name="creative writing,performing arts"]
[osec tag_id="1"]
[osec tag_id="1,2"]
</code></pre>
<p><strong>By post ID</strong></p>
<pre><code>[osec post_id="1"]
[osec post_id="1,2"]
</code></pre>
<h3>Requirements</h3>
<ul>
<li>WordPress: 6.6 or newer</li>
<li>PHP:
<ul>
<li>PHP 8.2+ required for development</li>
<li>PHP 8.1 may work for production builds when installed with <code>composer install --no-dev</code></li>
</ul>
</li>
</ul>
<h3>Languages</h3>
<p>OSEC supports multiple languages</p>
<h3>This Is a Fork</h3>
<p>OSEC is a fork of the GPL licensed plugin All-in-one-Event-Calendar by Timely. At it’s time a great plugin with a solid but unmaintainable codebase (not all required developer tools where opensourced).</p>
<p>If you love truly open source software and don’t mind to get your hands dirty you should join here. Free people need free software to manage and share events in a selfhosted manner.</p>
<h3>External services</h3>
<p>OSEC may connect to OpenStreetMap to render maps. If you using maps feature make sure you agree with <a href="https://operations.osmfoundation.org/policies/" rel="nofollow ugc">Terms of Service</a></p>
<p>OSEC may connect to OpenStreetMap Nominatim geocoding API. <a href="https://operations.osmfoundation.org/policies/nominatim/" rel="nofollow ugc">Terms of Service</a>.<br />
You may need to switch the servive on a heavy traffic site as Nominatim allows an <em>absolute maximum of 1 request per second</em>.</p>
<p>By default leaflet and leaflet-control-geocoder are loaded from unpkg.com. <a href="https://app.unpkg.com/policies@1.0.1" rel="nofollow ugc">Terms of Service</a>.</p>
<p>You can change using hooks: <code>osec_leaflet_library_alter</code>, <code>osec_leaflet_geocoder_library_alter</code>.</p>
<h3>Migration Notes</h3>
<p>Database structure is not fully compatible with All-in-One Event Calendar v2.3.4</p>
<p>Migration may be possible with manual effort</p>
<p>A standardized upgrade path may be developed if there is demand and contributions</p>
<p>See this <a href="https://github.com/digitaldonkey/open-source-event-calendar/wiki/migration-from-all%E2%80%90in%E2%80%90one%E2%80%90event%E2%80%90calendar" rel="nofollow ugc">wiki</a> for currently known information on migrating.</p>
<h3>Development & Support</h3>
<p>The principle behind this plugin is to be Open Source. Get in touch on <a href="https://github.com/digitaldonkey/open-source-event-calendar" rel="nofollow ugc">GitHub</a> to report issues, propose feature enhancements, and get general guidance for contributing.</p>
<p>Writing this fork was <a href="https://github.com/wp-plugins/all-in-one-event-calendar/compare/master...digitaldonkey:open-source-event-calendar:master" rel="nofollow ugc">a huge effort</a>.</p>
<p>Digitaldonkey believes everybody should be able to set up and manage public calendars.</p>
