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, no sync, and nothing transmitted.
