Calculate exact age

Age is often needed in years, months, and days rather than only a total number of years. This calculator compares the birth date with today or a custom date and returns a readable result.

How age is calculated

The calculator compares calendar dates and adjusts months and days when the target day or month has not yet been reached.

Why exact age matters

Some forms and policies require more than an approximate age, especially when eligibility depends on a specific date.
