Age Calculator

Calculate an exact age in years, months and days from a date of birth, plus the day of the week you were born.

How to use

  1. Enter the date of birth. The as-of date starts at today.
  2. The exact age in years, months and days appears, along with total days lived and the weekday of birth.
  3. The next birthday and the days until it are also shown. Change the as-of date to find the age on a past or future date.

Notes

The date of birth is processed only in your browser. It is never sent to or stored on a server. For February 29 birthdays, the birthday in a non-leap year is treated as February 28.
