Our age calculators use advanced date arithmetic to account for leap years, varying month lengths, and different calendar systems. When you enter a date of birth, our system calculates the exact number of years, months, and days that have elapsed, taking into consideration all calendar irregularities.
For example, calculating age from February 29 (leap day) to a non-leap year requires special handling. Our calculators automatically adjust for these edge cases to provide accurate results every time. Learn more about our methodology on our How It Works page.
