When using an undetermined date, I think the calendars will start in January 2001. Not so useful, I suppose.

The HTML export will create a folder, with a "calendars" folder inside of it. That should be full of .ics files. Either double-click one of those, or drag it onto the iCal icon in your doc. (Outlook and maybe Entourage should also be able to open these files, but that's probably beside the point.)
