How to share Birthdays from My Calendar that come from My Contacts with others.
I want to share birthdays of people in my contacts list with my spouse and show them in our mutual calendars. I primarily use Contacts on the Mac, but Contacts replicates via iCloud to my iPad and iPhone. This is an aggravating concern, as I keep the Grandchildren's and other important Birthdays on my Mac Calendar and she cannot see these dates.
