How old am I? Find your exact age

It sounds like a simple question, but "how old am I?" has two answers: the rounded number you usually give, and your exact age — years, months and days, counted to today. Enter your date of birth below and get the exact figure instantly, plus your total days lived and the countdown to your next birthday.

Why the exact answer is worth knowing

Most of the time the rounded year is enough. But licences, applications, insurance quotes, school admissions and pension forms ask for the precise figure — and milestones are more fun exact: 10,000 days old, 500 months old, or your next birthday in a specific number of days. This page gives you all of them from a single birth date.
