" Google Calendar added the same feature. Go to the Settings page, select the Calendars tab and click on "Browse public calendars", then add the calendar "Contacts' birthdays and events". Unfortunately, Google's built-in calendar doesn't support notifications."

job done and you should see birthday cake icons
