How your age is calculated
We count the full years, then the remaining months, then the leftover days between your date of birth and the chosen date — the same way you'd say your age out loud.
Frequently asked questions
Can I find my age on a future or past date?
Yes — change the "Age at date" field to any date to see how old you were or will be.
Does it handle leap years?
Yes, the calculation uses real calendar dates, so leap years are counted correctly.
