Find your exact age in years, months, and days from a date of birth, plus totals and a birthday countdown.
How to Use the Age Calculator
Pick your date of birth and your age appears instantly in years, months, and days. Leave the second date blank to use today, or set it to find your age on any past or future date. You also get total days, weeks, and months, plus a countdown to your next birthday.
