How is age calculated?
Age is the time between the date of birth and a chosen date, counted in full years, then leftover months, then leftover days. The calculator handles different month lengths and leap years, which is what makes doing it by hand error-prone.
Working out a birth year from an age
If you only know someone's age, subtract it from the current year to estimate the birth year. This gives a one-year range, because the answer depends on whether their birthday has happened yet this year.
