Finally, I’ve found a use for Facebook 🙂 This little tool will take all your friends’ birthdays and create an iCal file from them. The resultant URL can then be put into your favourite calendar program (I use Google Calendar), so you can see all your friends’ birthdays in one place.
This is very basic at the moment and I can’t guarantee it’ll be up and running for long (but I’ll try). It’s also very hacky, so expect nasty errors if something goes wrong!
Please give it a go if you have a Facebook account, and let me know if it works.
After this, FOAF extraction…. 🙂
