We (Marco, @CecileLG and I) created an event calendar in a spreadsheet format for relevant events for the open knowledge community.
The spreadsheet is in a format that can be imported to your Google Calendar, so give it a go!
If you see that we are missing events, please add them as well!
We have started in Austria an own calendar with all open events in AT, but also the most important international events. Maybe this is helpful: Open Events Ă–sterreich
I take this discussion on the events calendar to let you serious problem with the WordPress platform.
In the summer of 2013, a sysadmin installed at my request, the extension “Full Calendar Js” that worked very well with the WP version of the time. But after the great migrations of spring 2014, many extensions have been gradually uninstalled without notifying local webmasters.
Since 2015 until last week, I was very busy as a volunteer to coordinate and prepare the #OKFestMTL April 12 hosted by WWW2016.ca. My availability is now back to normal regarding the maintenance of the local group website in Canada.
The extension Full Calendar Js allows to integrate into a WordPress page many calendars in the Google XML format or --other XML / RSS feed.
It seems that the extension “Fullcalendar JS” no longer works for the API 3 Google calendar. In addition, this extension is valid till WP 3.9.1
I validate on my own site (dianemercier.quebec) other extensions to integrate multiple calendars and / or allow direct editing.
I will give the test results
I make Open Source software specially for communities listing events. It lets many people add events safely, then makes it easy to filter, view and export the data into all kinds of systems including Google Calendar. (We also have a WordPress plugin!)
I’ve copied the events from the spreadsheet into https://openknowledge.hasacalendar.co.uk/ - anyone can make a user account and add more events! Let me know what you think,
