What Is an Age Calculator?

An age calculator computes exact age — in years, months and days — from a date of birth, along with the total number of days lived and a countdown to the next birthday, handling the varying lengths of months and leap years automatically.

It's a quick way to get a precise age breakdown for a form, an eligibility check, or simple curiosity, without doing the calendar arithmetic by hand.
