How this tool works
Calendar age uses completed years, then completed months, then remaining days. Month-end anniversaries are clamped to the last valid day: February 29 becomes February 28 in a non-leap year. Date-only arithmetic avoids daylight-saving shifts. The end date must not precede the birth date.
