Description

Birthday Adapter brings birthdays, anniversaries, and other events from your contacts to your Android calendars. Unlike other apps, it creates a dedicated calendar within your system, so you can view all your contact dates alongside your daily schedule in your favorite calendar app.

FEATURES
* Address Book Based: Store birthdays directly in your contacts - no manual lists to maintain or duplicate entries to manage.
* Filtering: Choose which accounts or contact groups you want to see in your calendar.
* Integration: See your contacts' birthdays directly in your favorite calendar app, organized in a separate calendar that you can show, hide, or view alongside your daily schedule whenever you want.
* Age Display: With the age automatically being added to every event, you always know which milestone is ahead.
* Beyond Birthdays: Sync any custom-labeled date from your address book - perfect for keeping track of your contacts' anniversaries or their children’s and partners' birthdays.
* Reminders: Set as many reminders as you need for your events.
* Jubilee Markers: Spot major milestones and big anniversaries.
* Customization: Tailor event titles to your liking and choose which event types should trigger a notification.
* Personalization: Use the color picker to style your birthday calendar to match your personal preference.
* Background Sync: Your calendar stays in sync with regular updates in the background.
