How is age calculated exactly?

By comparing your date of birth to the "as of" date down to the day, giving a precise years/months/days breakdown rather than just subtracting birth year from the current year.

Can I calculate someone else's age, or age on a future date?

Yes — enter any date of birth and any "as of" date, past or future.

Does this work on Mac, Windows, or my phone?
