🎂 Calculate your exact age

How the age calculator works

Enter your date of birth and the date you want to calculate your age on (today by default). The calculator counts complete years first, then the remaining full months, then the leftover days — the same way age is calculated for official forms, admissions and job applications.

  • Admission and job forms: many forms ask for age on a specific date, such as the closing date of an application. Simply change the second date.
  • Leap years: if you were born on 29 February, 28 February is treated as your birthday in non-leap years.
  • Hijri birth date: shown using the Umm al-Qura calendar; local moon sighting may differ by a day.
