Age Calculator
Find your exact age in years, months and days.
Frequently asked questions
Why might my age be off by one day around my birthday?
This can happen due to how partial months are calculated when the day-of-month comparison is borderline — the totals (years/months/days) are computed independently from the total-days count.
Does this account for leap years?
Yes — it works from actual calendar dates via JavaScript's Date object, which correctly handles leap years.
