Question :
I just did a clean install of macOS on my Mac and everything works fine. Except for one thing…
The birthdays of my contacts are not showing up in Calendar.app even though they were properly showing in Calendar.app on my previous version of macOS and they are still showing up properly in Calendar.app on my iPhone.
I’ve already tried unchecking and re-checking the checkmark at “Birthdays” in the list of available calendars (at “Other”), login out of iCloud and back in, restarting my Mac, adjusting some birthdays in Contacts.app, etc. Simply put : I’ve tried any solution I could think of…
How can I fix this ?
Answer :
The solution might be simple, but easily overlooked :
in Calendar.app on macOS, go to “View” in the menu-bar and when the pulldown-menu appears, put a checkmark at “Show All-Day Events”, then click “Refresh Calendars”.
Now check if that solves your problem. If it doesn’t, try this :
- goto Calendar.app
- select Calendar (in the top menu-bar)
- select Preferences (from the pull-down menu)
- select General (the left tab)
- put a checkmark at “Show Birthdays calendar”
- note : if you already had a checkmark at “Show Birthdays calendar”, do this also :
- remove the checkmark
- close the Calendar-app
- restart your Mac
- open the Calendar-app
- put the checkmark back at “Show Birthdays calendar”
That’s it.
enjoy 😉

Yeah that didn’t work.
@Mario Segali :
Thanks for your feedback !
Sorry to hear this isn’t working for you yet…
Did you make sure that there is a checkmark at “Birthdays” in the “Other”-chapter (at the bottom) of the list of calendars at the left (that starts with the “iCloud”-chapter) ?
Hope this helps 😉
Enjoy !
In the “other” chapter, there is no option for “birthday.” It only shows “Siri suggestions” and “US Holidays.” I know I have entered all the birthdays in the contacts correctly because they show up on the calendar for my phone, just not my mac.
@Kin :
Here’s another suggestion for you :
goto Calendar.app > Calendar (in the top menu-bar) > Preferences (from the pull-down menu) > General (the left tab) > put a checkmark at “Show Birthdays calendar”
if you already had a checkmark at “Show Birthdays calendar” you can remove it, close the Calendar-app, restart your Mac, open the Calendar-app and put the checkmark back at “Show Birthdays calendar”
Hope this helps 😉

Your followup advice on 09-11-2020 is what worked for us on Catalina – thanks so much!
@schwie :
Great to hear !
Thanks for your feedback.
I will add that info to the original post also, so everyone reading this post will see it right away.
Thanks for the suggestion !
😉
Did not work here (macOS Monterey 12.5.1). Many of the birthdays are not shown in Calendar.
@Metty :
Thanks for the feedback !
Sorry to hear this doesn’t work for you (yet).
If this doesn’t work, there is probably a very small setting that you may have overlooked… biggest question : if so, which one ?
Have you made sure that you have all birthdays listed in the Contacts.app ?
And are you sure that the birthdays are in the ‘Birthday’ section of the Contacts.app (and not in the ‘Anniversary’ section) ?
If so, please try the redo option that is mentioned in the original post again…
hope this helps
Good Luck !
Wow! Thank you so much. It was checking the “Show All-Day Events” in the View pull-down menu that did the trick. It took a while for all the birthdays to show up, but they are all there now.
