Age Calculation
Age (years) = End Date Year − Birth Year, adjusted by −1 if the birth month/day has not yet occurred in the end year. Remaining months and days are computed from the calendar difference between the two dates.
Example
Born on 14 Aug 2000, calculated on 13 Jul 2026 → 25 years, 10 months, 30 days old.
