calendar

Hi Guys and Gals,

Im just wondering if there is a way to make mine and my wifes calendars sync together. We have different apple ID's. I know we invite each other and then accept and insert into each others calendar. Im just wondering if there is an easier way to automatically make the two calendars sync together. We have a 16 month old child and are both busy with work so we need t be on the same page at all times.

Any suggestions would be greatly appreciated.
