I have a family iCloud calendar that my wife and kids all access. With the iCloud control panel, I can see the family calendar on my (Windows 7) work PC side by side with my work calendar. For corporate security reasons, I can't push the work calender to iCloud. Also, the family doesn't want all my meeting alerts.
I'd like to be able to sync both calendars on my iphone (5s, so I'm stuck with iTunes 11).
