How this tool works

Age is resolved as complete calendar years, then complete months, then remaining days. Secondary totals derive from elapsed calendar days, and the next birthday follows the selected leap-day rule.

Limits to know

Calendar age is not a legal eligibility determination. Elapsed totals treat a calendar day as 24 hours and do not include a time of birth. Leap-day treatment, jurisdictional rules, and historical calendars can change a legal or cultural interpretation.
