About the Age Calculator
This tool calculates your exact age in years, months and days between two dates — your date of birth and any reference date (defaulting to today). It also shows total days, weeks and months lived, and how long until your next birthday.
FAQ
Does it account for leap years? Yes — the calculation uses actual calendar dates, so leap years are handled correctly.
Can I calculate age as of a future or past date? Yes — change the "As of" field to any date you like.
