Most of the time you will use KOrganizer to view your calendar data, but imagine you would like to publish events, meetings or tasks in the Intranet or on the World Wide Web. KOrganizer can do this for you.
Choose "Export > Export Web Page" from the FILE menu and follow this dialog:
KOrganizer generates web pages from your calendar and todo data, which can be viewed with any web browser.
This makes it easy to let your colleagues know about upcoming meetings, publish events like lectures and football games or just let you access your calendar from everywhere where you have access to the Internet or Intranet.
