DOES THE RESULT LOOK WRONG?
HOW IT WORKS
Calendar age cannot be found by dividing elapsed days by 365 because months and years have different lengths. This calculator subtracts years, months and days in sequence and handles leap years automatically.
FREQUENTLY ASKED QUESTIONS
Yes. The calendar calculation and total-day count automatically include every 29 February crossed by the selected dates.
Yes, provided the reference date is not earlier than the date of birth.
RESULT GUIDE
The method performs calendar subtraction rather than using an average year length, so the result remains meaningful in years, months and days.
Age = reference date − date of birth, split into years, months and daysIf the reference day is earlier than the birth day, the correct number of days is borrowed from the previous month; the same principle applies to months and years.
The separate total-day result uses actual calendar days, including leap days.
