I've never been able to get gcal to work - no matter what I type, I get "Nothing found.", but I don't have any idea how it's supposed to work, either. When I installed the czb pack, I got some html help files, but with the exception of JSCalc, all the help topics just say something about typing in text for the "New Tiddler". Does anybody else have it working, or know how it's supposed to work?
