About this calculator
This calculates exact age by counting full years, then full months within the remaining period, then remaining days — the same way age is calculated for legal and official purposes, rather than just subtracting years.
Why does my age in days seem different from years × 365?
Leap years add an extra day roughly every four years, so total days lived is always a bit higher than a simple years × 365 estimate.
