Add event to multiple calendars?

Realize this is an old thread, but I was looking for the same information. The solution I use is to add my other email address as an invitee on the appointment. That allows you to see the event in both calendar and also replicate out any updates.

You can share calendar with your family members ( wife as in your question ) with the help of this article : Calendar (El Capitan): Share calendar accounts

And add an event to family calendar you have to first join the family member : macOS Sierra: Join a family

Then add an event to your family calendar : macOS Sierra: Add an event to the family calendar

And regarding your exchange calendar account with your staff or others : https://support.apple.com/kb/ph22690?locale=en_US

If your calendars are administered through Microsoft Exchange Server 2007 with Service Pack 1 or later (for example, through your workplace), in Calendar you have a main Exchange calendar named Calendar.

You can add calendars to your Exchange calendar account, but you won’t be able to see updated invitations or attendee responses for events in those calendars. Also, events in the additional calendars won’t be visible to delegates (people who share your calendar account) and won’t appear when users check your availability. Full calendar features are available only in your main Exchange calendar.

So, both family calendar & exchange calendar are different .And if you are messing with up the calendar with events in both accounts you can change the colour for calendar accounts ( right click on the account ) .

Hi Robert,

There is not. If you would like this as a feature I sugget sending feedback to Apple. http://www.apple.com/feedback/
