Friends, would you like to synchronize your Facebook events with your Google calendar? As is well known, Facebook offers the option of exporting and synchronizing all events in a third-party calendar application such as Google Calendar, Apple Calendar or Outlook. But no matter what you do, it just won't work with the standard functions?
The reason is that Facebook also exports events that have not yet been replied to. Since Google and other providers validate the iCal file more precisely than Facebook exports it, errors occur during import or synchronization. Simon Bengtsson has a web application called «Facebook Events Calendar» which filters the Facebook export and deletes the erroneous events. By the way, you can find the source code here Github. If you don't know exactly which URLs we're talking about and where you can find them on Facebook or how to get them into the Google Calendar here are instructions to. As an intermediate step, simply clamp Simon's filter in between and finally the synchronization works again as it should!
