How the Age Calculator Works

Enter your date of birth and Agevly calculates your exact age today. It counts real calendar days, so leap years and months of different lengths are handled correctly, and it updates every time you open the page.

Calculate Age in:

  • Years
  • Months
  • Days
  • Weeks
  • Hours
  • Minutes

Example

Someone born on 15 March 1990 is, as of 28 September 2026, 36 years, 6 months and 13 days old. That is 438 months, 1,906 weeks, 13,346 days, 320,304 hours or 19,218,240 minutes (counted from midnight).

Frequently Asked Questions

Q: How do I calculate my exact age?
A: Enter your date of birth into the calculator above. It counts the real calendar time between your birth date and today, so you get your age in years, months, days, weeks, hours and minutes.
Q: Does the age calculator handle leap years?
A: Yes. It uses actual calendar dates, so leap days and months of different lengths are counted correctly. A rough years times 365 estimate always undercounts.
Q: What is chronological age?
A: Chronological age is simply the time that has passed since you were born, as opposed to biological age, which describes how your body is ageing. This calculator gives your chronological age.
Q: How old am I in months, weeks or days?
A: The same calculation shows all of them at once: total months, weeks, days, hours and minutes lived. For a single unit, try our Days Alive Calculator.
Q: Can I calculate age on a specific date?
A: Yes. Use the Age on a Specific Date calculator to find how old someone was, or will be, on any past or future date.
Q: Can I use it for someone else?
A: Yes. Enter any date of birth, whether it's a child's, a relative's or a public figure's.
