The Calendar-ID is the short, unique identifier for your FamilyTimePlanner. (e.g. smith1) This cannot be changed once the calendar is created.
The name appears on the calendar to the left of the Day tab. (e.g. Welcome!) This can be changed at any time.
The zip code (or country code for non-U.S.) is to allow Family Calendar users to find local Club calendars. *Only required for Club calendars.
