iCal is another name for a technology called iCalendar. iCalendar is the language that many calendars use to import and export events and appointments. There is a very helpful wikipedia article on the subject.

According to the article iCalendar is supported by the following calendaring applications:

• ScheduleWorld
• Korganizer
• Mozilla Calendar (including Mozilla Sunbird)
• Mulberry
• Ximian Evolution

For the widget-hearted, you can download iCalendar widgets that will give you one-key access to your tourfilter calendar.

• For Mac users (OS X 10.4 and up), you just need to download Ben Kazez's iCal Events widget.
