Age Calculator
Calculate age from a birth date to today or another age-on date, with years, months, days, total days, and birthday context.
Age on the selected date
Enter the birth date and the date on which age should be calculated. The result counts completed years first, then the remaining months and days.
A birth date of 2000-01-01 and an age-on date of 2026-07-21 produces 26 completed years plus the remaining calendar span from January 1 to July 21. A future birth date is invalid.
Calendar interpretation
This is calendar age, not an exact elapsed-hour total. Month lengths and leap years affect the remainder. The input contains dates only, so birth time and time zone are not part of the calculation.
