How Age is Calculated
This age calculator computes age on three standard chronological dimensions: years, months, and days. It handles leap years correctly (e.g. accounting for the extra day in February during leap years) to provide a 100% precise time metrics breakdown.
Chronological Age vs. Calendar System
Standard calendar systems count age based on actual calendar days rather than exact astronomical years. This means if you are born on February 29th, your age will only increment on February 29th in leap years, or on March 1st in non-leap years. This tool fully adheres to standard legal chronological age computation rules used in the US, India, UK, and European agencies.
