Refer to instructions for setting up RSS for the Event Calendars and Weblogs. Once you have enabled RSS, follow these instructions to find your RSS feed URL:
  1. Browse to your Event Calendar page or Weblog page
  2. If browsing to your Event Calendar page, click the Published Events link above your calendar. Otherwise, go to step (3)
  3. Next to the title of your page near the top, you'll see the orange/white "RSS" icon
  4. If you click this RSS icon, the address that you'll be taken to is the RSS feed URL for that Event Calendar or Weblog

You can then use this RSS URL/address anywhere that RSS feeds are allowed.
