I volunteer and provide technical support for a few non-profits, one of which is the Project Management Institute San Francisco Bay Area Chapter (http://www.pmi-sfbac.org) where I serve as the VP of Operations and CGO.
One of the moves I made in my first year with them was to migrate our event calendar to Eventbrite and Meetup. One of the gaps I found with Eventbrite is that it doesn’t have a way to provide a feed of events that can be used to update an external calendar, so I embarked on a little programming effort to create one.
Most calendar programs allow you to pull external events using the iCalendar (ics) format, and Eventbrite actually has a pretty decent API to allow you to pull the events, so I decided to write a simple PHP script to allow me generate an iCalendar feed.
This started as a simple one-off for PMI-SFBAC, but has turned into an open source project at https://code.google.com/p/eventbrite-ics/
Looking at the code, you can see it’s pretty basic, just a few PHP classes, some unit tests, Netbeans project and data.
Once the code was working, I used the iCalendar validator at http://severinghaus.org/projects/icv/ to make sure the results are good, and (at least for PMI-SFBAC) they are.
Eventually this results in a URL that I used as a feed into the All-in-One Calendar from Time.ly which lets me show events on my site’s calendar along with any other iCalendar feeds I choose to add.
To configure the All-in-One calendar, I just go to the Events in the WordPress admin panel, and add the feed.
After I add the feed I click the “Refresh” button to make sure the events show up on my calendar immediately. The events then get updated on a periodic basis (daily by default), and should keep you up to date.
Another use I put this feed to is to add the Eventbrite calendar to my Google Calendar. I have a calendar feed from Meetup, and several of my friends so that I can quickly see what is going on that day.
The same basic idea for Google Calendar: you go to your Google Calendar, click the drop down on “Other Calendars” and choose “Add by URL”.
This gives you a nice view of events so that when you are scheduling things you can see what’s coming up that you might be interested in.
For those of you poor souls still using Outlook, the same feed can be used there as well see: http://office.microsoft.com/en-us/outlook-help/view-and-subscribe-to-internet-calendars-HA010167325.aspx
