Find your exact age in years, months, and days — free, private, instant.
Total days lived: 0
This calculator finds the exact time between two dates — typically your date of birth and today — broken down into full years, full months, and remaining days, rather than a single decimal figure. It's useful for anything that requires a precise age on a specific date: eligibility checks, legal or medical forms, or just satisfying curiosity about exactly how old you are down to the day. It also works for any two dates, not just birthdays, so you can use it to find your age as of a past or future date.
Enter your date of birth, and optionally change "Calculate age as of" to any other date, then tap Calculate age to see your exact age broken down into years, months, and days, plus total days lived.
How is my age calculated?
We count full years, then full months, then the remaining days between your date of birth and the "as of" date — the same method used by most official age calculators.
Can I find my age on a specific past or future date?
Yes — change the "Calculate age as of" field to any date to see your age at that point in time.
