Frequently asked questions
How is my exact age calculated?
The calculator counts full years, then the remaining full months, then the leftover days — the same way you'd say your age out loud. Leap years and varying month lengths are handled automatically.
Does it work for any birth date?
Yes, as long as the date isn't in the future. It handles leap-day births and dates from any year.
