About Age Calculator

Enter a date of birth and see the exact age on today's date or any other: years, months and days, the totals in months, weeks and days, the weekday you were born on, and how long until the next birthday and which weekday it falls on.

For people born on 29 February you can choose whether the birthday counts as 28 February or 1 March in common years - customs and laws differ. Ages are counted in whole calendar days; the time of birth is not used.

How to use it

  1. 1Enter the date of birth.
  2. 2Leave "Age on" as today or pick another date.
  3. 3Read the exact age, totals and next birthday; copy the result if you need it.
