Age Calculator

A free age calculator that works out an exact age from a date of birth. It reports age the way people say it — years, months, and days — and also as running totals of months, weeks, and days for forms and milestones. By default it measures age as of today, but you can set any reference date to find age on a past or future day. The calculation uses whole calendar days and accounts for leap years, so the result is precise. The birth date is processed in your browser and never stored.
