About
Calculates exact age in years, months and days, accounting for leap years. Fast and no sign-up, right in the browser.
How to calculate your exact age
UtilNexo's age calculator shows how many years, months, and days you are based on your date of birth, without manual counting or a calendar.
The calculation considers the difference between today and the birth date, respecting the order of months and leap years. If you were born on 03/15/1990, on 08/13/2026 you will be 36 years, 4 months, and 29 days old.
The tool is useful for filling forms that ask for exact age, checking benefit eligibility, calculating legal milestones, and tracking child growth in months.
Examples
- Born 03/15/1990, today 08/13/2026 → 36 years, 4 months, and 29 days.
- Born 01/01/2000, today 01/01/2026 → exactly 26 years.
Limitations
- The result follows the civil calendar and the browser's local date; it does not account for a specific birth time zone.
- The calculated age is informational and does not replace an official document.
