How this works
The calculator takes your date of birth and today's date, then works out the full years, remaining months, and remaining days between the two dates — accounting for varying month lengths and leap years.
Frequently asked questions
Why does my age in days not match years × 365?
Leap years add an extra day roughly every four years, so the exact day count is always a little higher than a simple 365-day multiplication.
Is my date of birth stored anywhere?
No — the calculation happens entirely in your browser and nothing is sent to or stored on any server.
