FAQ

Q: Can I use my favorite calendar app with Birthday Adapter, or do I have to use a specific one?

A: You can absolutely keep using your favorite calendar app. Birthday Adapter integrates directly with the Android system calendar database rather than forcing you into a proprietary viewer. This means whether you prefer Google Calendar, Outlook, or any other third-party calendar app, your contacts' special events will seamlessly appear as a dedicated layer that you can easily toggle on or off.

Q: Will the calendar show me how old someone is turning on their birthday?

A: Yes, it will! One of the most convenient features of the app is its ability to calculate and display the exact age or the specific anniversary year right on the calendar event. You will always know at a glance whether your friend is turning thirty or if a couple is celebrating their fifth wedding anniversary, helping you send the perfect message.

Q: Does Birthday Adapter only track birthdays, or can I add other types of events?

A: While birthdays are in the name, this versatile app tracks a wide variety of dates. It easily handles wedding anniversaries, partner dates, and even custom-labeled milestones that you have saved in your contacts. This makes it a complete, all-in-one celebration manager for all the relationships in your life.
