Age Calculator
Calculate exact age in years, months, days, and total days from any birth date.
Select your birth date to calculate your age
Subtracting a birth year from the current year gets the wrong answer more often than it seems like it should, if today's date falls before this year's birthday has actually happened yet, that simple subtraction overcounts by a full year, an easy mistake that only shows up as a wrong result rather than an obvious error. This tool calculates exact age in years, months, and days from a birth date, correctly accounting for whether this year's birthday has occurred yet, and also reports total days lived.

Useful for getting a precise age broken into years, months, and days rather than a rounded year count, calculating exactly how many total days someone has been alive, or confirming an age calculation is correct for a date near someone's actual birthday when simple subtraction would get it wrong.
