Requirements

Before you get started subscribing to the calendars, you must have a specific piece of software downloaded to your computer. On a Macintosh computer you should use iCal, and on a Windows machine a program called Sunbird is recommended.

Macintosh
iCal - If you are running OS 10.2.3 or later, you probably already have iCal installed on your computer. If not and you need to download, go to http://www.apple.com/ical/
You need Mac OS X version 10.2.3 or later to use iCal.

Windows
Windows requires third party software to view iCal Calendars.
A popular and free choice is Sunbird. You can find more about Sunbird at http://www.mozilla.org/projects/calendar/sunbird_download.html
Other third party software products are available for Windows. All you need is a calendar application that supports the iCalendar standard. Additional options include Microsoft Works (version 8 or higher), WinDates, EventSherpa, and Mozilla Calendar. The instructions for adding calendars to these programs is similar, but you will need to check their manuals for specifics.
