How the Age Calculator Works

The age calculator takes your date of birth and compares it with today's date. It counts the full years first, then the remaining months and days. This is the same method used on official forms, school admissions and job applications, where your exact age matters.

For example, if you were born on 1 January 2000 and today is 14 November 2026, you are 26 years, 10 months and 13 days old. The calculator does this subtraction for you in one click, so you do not need to count months and leap years by hand.

You can use this tool to check your age for a passport, ID card, exam form or job application. It also helps parents check a child's age for school admission. The calculation happens in your browser and on this page only — your date of birth is not saved or shared anywhere.
