FAQ
How is age calculated exactly?
The calculator counts full years, then the remaining months, then the remaining days between your birth date and the chosen date.
Does it include leap years?
Yes — the total-day figure counts every day, so leap years are included automatically.
Is it private?
Yes. Everything runs in your browser; nothing is uploaded.
