Quora Answer: What is the best solution to share a single calendar between two people on their iPhones

"I am sure someone else will say .Mac/.Me, but I have found that using Google Calendar, along with its sharing and syncing options works pretty well for me. We have 3 Macs and 2 iPhone syncing together and sharing calendars among myself, my wife and my son. The shared calendars greatly help us manage our schedules which change quite frequently as I am a freelancer and my wife an adjunct college professor at 4 different school. My 12 year old son adds even more into the mix with school, after-school activities and his interest in archery and other pursuits.

?

My set up includes 3 separate Gmail accounts which then share their calendar with the others. These accounts are then used to sync the iphones where needed. I can add/edit items in my own calendar, as well as theirs.

In the left hand column, next to the name of your calendar, click the down pointing arrow and select Share this calendar by entering the email address of the person you want to share with. Have your wife do the same. At that point, your calendars are linked and both can be synced to your iPhones.

My best recommendation comes from a typical scenario where we are both at work and I can add an appointment I scheduled while at another clients and my wife sees that new appointment immediately in her Google Calendar. It really helps to cut down on cross-scheduled appointments and other confusion."
