Get a birthday calendar for all your social networks right inside your calendar app (such as Google Calendar). Supports all apps which sync contacts with your Android device, that includes many social network and messaging apps. Enable reminder alarms and decide which contacts you want to see. You'll get notifications for all of them.
The birthdays in the app are listed as a day behind.
E.g. a birthday on Dec 9 appears as Deb 8 in the app.
The event that appears in my calendar and the contacts apps seems fine though. Specifically the only issue is that it shows wrong if I open the BirthdayCalendar app, but everything else is correct. Perhaps it's a timezone issue? For reference, my local timezone is GMT-5.
