Q: How do I create a shared calendar over multiple phones

Hey scwalters101,

You can create a shared calendar and use the iPhone's Calendar application for viewing, creating and changing it. In order to do so you also need a calendaring service. Many are available, including Apple's iCloud. See this page for information about iCloud calendars -

Thanks for using Apple Support Communities.

Be well,
