Technical Note: Database Architecture
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.
<h3>External Services</h3>

<h4>Nager.Date API</h4>

* <a href="https://date.nager.at/LegalNotice" rel="nofollow ugc">Terms of Use</a> 
* <a href="https://date.nager.at/Privacy" rel="nofollow ugc">Privacy Policy</a>
<h4>Google Calendar Public Feeds</h4>
Alternative holiday source. Fetches public .ics files from Google.

<h4>Remote Calendar Sync (User-Configured)</h4>
When remote iCal subscriptions are configured, the plugin fetches .ics data from 
those URLs via HTTP GET. No user data is transmitted to these services.
<h4>OpenStreetMap / Nominatim</h4>
When a single event page has a location and the map provider is set to OpenStreetMap 
(the default), the plugin geocodes the address via the Nominatim API and displays a 
map using OpenStreetMap tile servers. The event location string is sent as a search 
query. No user personal data is transmitted. 
* Geocoding endpoint: https://nominatim.openstreetmap.org/search

* <a href="https://wiki.osmfoundation.org/wiki/Privacy_Policy" rel="nofollow ugc">OpenStreetMap Privacy Policy</a>
<h4>Google Maps Embed API</h4>
When the map provider is set to Google Maps in settings, single event pages display 
an embedded Google Map for the event location. The event location string and your 
Google Maps API key are sent to Google. No other user data is transmitted. 
* Endpoint: https://www.google.com/maps/embed/v1/place

<h4>Add to Calendar Links</h4>
Single event pages include “Add to Calendar” buttons that generate links to Google 
Calendar, Outlook.com, and Yahoo Calendar. When a visitor clicks a button, the event 
title, date, time, location, and description are passed as URL parameters to the 
chosen service. No data is sent until the visitor clicks.

<li><code>build/</code> — the pre-compiled minified bundles (what the plugin actually loads at runtime)</li>
<li><code>package.json</code> + <code>package-lock.json</code> — Node build manifest and lockfile for reproducible <code>npm install</code></li>
<li><code>composer.json</code> — PHP dependency manifest</li>
</ul>

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

Add the calendar you already use to Any WordPress site! Google Calendar, Microsoft 365, iCloud and more… no API keys or complicated setup required.
