About the Age Calculator
The Age Calculator works out the exact time between two dates in years, months and days, plus the total number of days. With a birth date and today's date, that is your exact age.
Everything runs in your browser with JavaScript. Nothing you type is uploaded to our server, so it is safe to use with private data.
