Check whether the birthday comes from the contact card
A birthday shown in Calendar can come from a birthday field on a synced contact. Confirm the source card before changing calendars or deleting an unrelated event.
Review the affected contacts and remove only the birthday field, leaving names, phone numbers, emails, and other useful details unchanged.

No when the cleanup is limited to the birthday field. Review the preview to confirm that the contact and its other fields remain unchanged.
