How Age Calculator works

Enter your date of birth. The calculator counts full years, then the extra full months, then the leftover days up to today (or any date you choose).

It also shows your age in total months, weeks and days, the weekday you were born, and how many days are left until your next birthday.

When it helps

  • Filling government, school or job forms that ask for age on a certain date
  • Checking if you meet an age limit on a cut-off date
  • Finding a child's age in months for vaccination or school admission
  • Planning a birthday countdown

Frequently asked questions

Is the age calculated on a particular date?

Yes. Leave the second date as today, or pick any date, such as a form cut-off date, to see your age on that day.

How are months and days counted?

It counts full calendar months from your birth date and then the remaining days, the same way most forms expect.

Is my date of birth saved?

No. The calculation runs in your browser and nothing is sent or stored.
