WHY AGE CALCULATOR?

"How old am I, exactly?" sounds like a simple question until you try to work it out across leap years and uneven months. Age Calculator does the arithmetic for you and keeps going — down to the minute — and refreshes live so the number is always current. Beyond your own age, it counts down to your next birthday and tells you which weekday you were born on, all from a single birth date on one screen.

Saved profiles make it just as quick for everyone around you: store birth dates for family members and switch between them with one tap, perfect for tracking a baby's age in weeks or remembering exactly which milestone birthday is coming up. Every birth date you enter stays on your device — there's no account and no sync.

Recent changes:
Birthday countdown now agrees with your age for Feb 29 birthdays: in non-leap years both treat Feb 28 as the day. The Edit and Remove buttons are easier to read, and the profile chips and the add button are bigger and easier to tap. The "removed" message now disappears on its own after you delete a profile.
