The tool counts full calendar years between the two dates, then the leftover months, then the leftover days — the same way you would read an age or a length of service, not as a raw day count divided by 365.
Only the calendar dates matter; the time of day is ignored. Leap days are handled by the calendar itself, so a span crossing 29 February counts correctly.
That is the promise behind every tool here. Files are read in your browser tab, processed there, and discarded when you close it — never uploaded to our servers.
