Birthday Adapter

Syncs contact birthdays and anniversaries into your Android calendar

Mobile appfreeglobal

Birthday Adapter is a free, open-source Android app that syncs contact birthdays, anniversaries, and other events directly into the standard Android calendar. Unlike standalone birthday-reminder apps, it integrates with the system calendar so important dates show up alongside other events. It's for Android users who want one calendar rather than a separate birthday-tracking app.
