You can choose a specific calendar category by clicking on the small triangle in the upper right corner of the calendar.

If you already use Google Calendar (or wish to — it’s free), click the plus (“+”) sign in the lower right corner and you will be “subscribed” to this calendar.

If you use Apple iCal, MS Outlook, or any other application that uses standard iCalendar “.ics” format, you can subscribe to the FEELC calendar, too. In iCal, choose “Subscribe…” from the Calendar menu and then enter the URL:
https://www.google.com/calendar/ical/feelc%40verizon.net/public/basic.ics
Change the “auto-refresh” setting from “no” to something reasonable, such as “Every day”.
Don’t download the basic.ics link above and double-click on it; that will give you a ‘static’ calendar that does not reflect updates.
