Calculate exact age (years, months, days) from a birth date.
Forms want an exact age, and 'about thirty-four' won't do. Give it a birth date and it returns the precise years, months, and days — the version you need for a visa application, an eligibility cut-off, or a school admission form.

Good to know: It counts calendar-aware, so leap years and months of different lengths are handled properly rather than by dividing the days by 365.25 and hoping.
Common questions
Why not just divide the days by 365?
Because it drifts. Dividing by 365 (or 365.25) ignores which months a span actually crossed, and over a few decades it can be a day or two out — which is precisely the kind of error that matters when a form has an age cut-off. This walks the calendar instead, so the answer is the one a registrar would give.
