Hi Juerg,
Sorry but no, the Event Calendar Pro feature is not designed to be on multiple pages.
Part of the reason for this is so that page permissions can be enforced consistently and part is because it generates friendly urls for events like event-name.aspx and these map to a real url (example ~/Events/ViewEvent.aspx?pageid=2&mid=2&ItemID=2) that uses the same pageid every time.
The view pages also must pass the same page id, ie /Events/WeekView.aspx?pageid=2&mid=2
Best,
Joe
