How to use Age Calculator

Common questions

Does it handle leap years?

Yes. Month and day calculations account for varying month lengths and leap days.

Future birth dates?

Invalid or future dates produce a clear result or zero age depending on inputs.

Timezone sensitive?

Uses local calendar dates from your browser — fine for personal age, not legal timestamp proof.
