            || today.getMonth() != nearest.getBirthday().getMonth()
            || today.getYear() != nearest.getBirthday().getYear()) {
            age++;
        }
        nearestJLabel.setText(nearest.getName() + " (" + age + " years old) in " + nearest.getDaysRemaining() + " days");
    } else {
        nearestJLabel.setText("There are no persons in the list.");
    }
}

If there are any persons in the person manager, we'll find
