About
An age calculator is a practical way to find your exact age for official applications, birthday planning or simple curiosity. Accounting for calendar month and day differences gives a more reliable result than a simple year subtraction.
Just pick your date of birth; the tool breaks down the elapsed time into years, months and days. The calculation runs entirely in your browser.
How to use
- Select your date of birth from the calendar.
- Your age is calculated instantly in years, months and days.
- Try a different date to update the result.
Frequently Asked Questions
- How is age calculated?
- Your date of birth is subtracted from today's date, with month and day carry-overs corrected against the calendar to give exact years, months and days.
- What if I enter a future date?
- The date of birth can't be after today; in that case no result is shown. You need to enter a valid past date.
