Update (2012-08-02): Visit http://icalfilter.com/fbfix.php and paste the url to get the url for the corrected calendar.

When exporting your Facebook Events feed to webcal/ical/ics, the whole day (no given time) events are one day early. Until Facebook decides to fix this, I have created a proxy script. Just supply it with the same uid and key as in Facebook's version and it will correct these errornous events.

It works like a charm for me, but let me know if you are having trouble using it. Also check out http://icalfilter.com and see if it might be something for you as well.

It recently got harder to remove yourself entirely from a Facebook event (not just declining/joining the not going-party. There used to be a link "remove from my events" or something similar on the event page but it seems to have disappeared. Instead, you have to

1. decline the event
2. click on one of the going/maybe/invited labels in the left menu
3. select declined from the list
4. find yourself and press the cross to remove yourself from the event

I posted this here because I couldn't find a good guide on the web but managed to find out how to do it anyway. Hopefully, it will help some of you people out there.

Cheers,
Emil
