How to add The Reef's calendar to your own calendar app

This is a wiki, with full revision history functionalities. Edit at will.


The Reef has its own calendar, called “The Reef meetings”. It lives in the Calendar app of The Reef’s Nextcloud: to access the calendar app, simply click on the Calendar icon in the blue bar on the top of Nextcloud’s interface. It is shared with the group called Everybody, with edit privileges. This means that all Reeflings can add, delete of change events. Do this with care!

You can also access the calendar by navigating to its URL:

In fact, anybody can see the calendar with a browser, but only Reeflings logged into Nextcloud can make changes to it.

You are welcome to use Nextcloud as your own calendar app. However, many of us already use other calendar apps, like Google Calendar. If you are in this situation, we recommend adding The Reef’s calendar. This will make it easier for you to be aware of your commitments with The Reef when you make your own scheduling decisions.

The documentation to NextCloud’s calendar app is here.

Adding The Reef’s calendar to your calendar app

To add The Reef meetings calendar to your own Google Calendar application, do this:

  1. Go to and log in.
  2. In the sidebar under “Other calendars”, click “+” and then “From URL”.
  3. In field “URL of calendar”, enter: Notice that this URL is different from the one above.
  4. Click “Add calendar”.
  5. Make sure that the option “Sync calendar” in your app is checked. They look a bit different depending on the app. On the Google Calendar Android app normally the imported calendars do not sync by default, so you have open the calendar settings and enable syncing. Settings => list of calendars, then click on “Show more” => locate the “The Reef meetings” calendar, click on it, then click on “Sync”.

Now the events of that calendar appear in your Google Calendar. (Easiest way to check: open three-dots menu for calendar “The Reef meetings”, then choose “Display this only”.)

Calendar apps other than Google will work in much the same way. As always, ask @manuelpueyo or @Pieter myself if you need help.
