I'm cleaning up my Mac in preparation for Mavericks and noticed I have 7 calendars in iCloud but really only use 4. The ones I don't use are Home, Work, Calendar, and David... but one of them for sure has events in them. Is there a way I can check the others? I'd hate to delete say Work and end up losing a lot of previous older stuff. I've tried the Get Info and there's nothing that says how large it is or anything. Any ideas?
