So here's my problem. I've been struggling all afternoon with an effective way to mark up this as an hCalendar event: http://greatisland.ca/calendar/test.html As you can see, there are three different occurences of the same event. I tried the RDATE method from hcalendar-brainstorming on the wiki but it wouldn't parse properly. Any ideas as to how one would go about this? Thanks in advance.
