Display calendars from on your site.

Basic usage

This WordPress plugin allows you to embed any calendar hosted on on your WordPress site.

Upon activation, the plugin creates a new post type named Calendars. Just create a new calendar, provide the UID of the calendar you wish to display in the calendar settings box, and that’s it !

You can leave the content area for this calendar empty, as it will be populated automatically with your events !

Your events are automatically inserted after your content. If you wish to control where your events will be listed, just use the shortcode [openagenda] in your content.


General settings

General settings can be found under the Calendar > Settings entry in the admin menu.

All data related to your API key or calendars can be found on

The main settings page provides the following settings :

  • Open Agenda API key : Your user API key. Providing your account API key is required for the plugin to work properly. It can be found in your account on
  • Allow for embedded content : If your events contain embedded content, tick this box to allow the corresponding HTML tags.
  • Load default stylesheets : The plugin provides very basic styling and depends heavily on your theme’s styles. Disable this to rely 100% on your theme styles.
  • Cache duration : For performance reasons, basic requests to Openagenda are temporarily kept in cache. This settings controls the time to keep them cached, in seconds.
  • Delete all calendar content on uninstall ? : controls whether you want to delete all your content on uninstall.

Integrations settings

The Integrations tab allows you to fine tune settings for various third party services the plugin uses.

    Permalinks settings

In the Permalinks settings, you can change the prefix for your calendar pages. You cannot leave this blank as your URLs will conflict with WordPress’ default pages and posts.

To integrate filters directly in your content instead of widget areas, the plugin also provide shortcodes.

Every shortcode listed here (except for [openagenda]) corresponds to a filter option in the widget.

Additionaly, shortcodes and widget filters have the same parameters, and every shortcode attribute corresponds to a widget filter setting.

J'utilise régulièrement OpenAgenda pour afficher des Agendas sur les sites de mes clients. J'utilise généralement le systeme des Iframes OpenAgenda mais cela a ses limites. Avec ce plugin trés intuitif et facilement personnalisable, je peux créer des intégrations bien plus poussées très simplement en créant mes propres templates. Parfait pour un intégrateur WordPress !

I find this plugin quite neat indeed. Any wordpress user can easily add dedicated agenda pages powered by the OpenAgenda platform. Little disclosure: I work for OpenAgenda.
