Birthdays / Anniversaries are not showing up

Check the Contact's Date Label

For a wedding anniversary or another annual anniversary, edit the contact in Apple Contacts or BusyContacts and choose the built-in anniversary label from the date's label menu. Custom labels such as Wedding, Wedding Anniversary, or Other are not included in BusyCal's Anniversaries calendar.

For birthdays, use the contact's birthday field. Enter the original date and save the contact. BusyCal repeats birthdays and anniversaries every year.

BusyCal

Open BusyCal > Settings > General:

1. Enable Show Birthdays calendar and/or Show Anniversaries calendar.
2. Set Contacts from to the app containing the contact and its date. Choose Apple Contacts if you do not use BusyContacts, even if BusyContacts is installed.

If you choose Apple Contacts, also open System Settings > Privacy & Security > Contacts and allow BusyCal access to your contacts.

If the date is still missing after checking its label, source, and the BusyContacts setting below, refresh the calendars:

1. Turn off Show Birthdays calendar and Show Anniversaries calendar in BusyCal's General settings.
2. Quit and reopen BusyCal.
3. Enable the calendars again and allow time for them to refresh.

BusyContacts

When BusyContacts is the selected source, edit the contact and make sure show dates is checked. This controls whether that contact's supported dates appear in BusyCal.

If the checkbox is missing, enable Show Dates in Calendar under BusyContacts > Settings > Info Panel, or add it to the card using the add field menu. The contact must contain a date field for the checkbox to be available.

This setting is local to each Mac. It does not make custom date labels appear in BusyCal. See Show Dates in Calendar.
