title: How do I create a link to add an entry to a calendar?
body: <p>I'm working for this nightclub and are currently making a website for them, they've got lots events and their site is built a lot around events, today they make an facebook event of every event but it would be killer to have a "Add to my Calendar" button which added it to your iCal or Google Calendar (or maybe even Outlook).</p>
  
  <p>I've managed to figure out how to make an calendar feed but then it will be added as a new calendar, only good thing is that people can "subscribe to events" but it's quite messy to have an calendar for every event. So I would like to know how to implement a function which lets them add it to their main calendar easily. Think like a mailto: link but for calendars if that's possible.</p>
  
  <p>Also while I'm on the subject, does anyone know if it's possible to automatically import an event from Facebook to WordPress or export an event from WordPress to Facebook that would be great, but that's not so important.</p>
