Find your exact age in years, months, and days — and see how many total days you've been alive.
This calculator counts complete years, then complete months within the current year, then remaining days — the same way age is conventionally stated, rather than just dividing total days by 365.
Leap years add extra days roughly every four years, so total days lived is always slightly higher than years × 365.
Yes — change the 'Age at date' field to any date to see age as of that point, useful for eligibility or milestone calculations.
