Calendar Configuration Details
To subscribe you need to use a calendar program that accepts iCalendar (.ics) formatted calendars (sometimes called iCal format). Common programs that accept iCalendar formatted calendars are Microsoft Outlook (for Windows computers), iCal (for Macintosh), and Google Calendars.
Each program will have different steps you need to follow to subscribe and update the calendars on a regular basis. Consult your preferred program’s help documentation for information about how to configure your program.
Be sure to configure your program to receive automatic updates.
