Age Calculator
Calculate exact age from a date of birth online for free — years, months and days, total days lived, and a countdown to the next birthday.
Frequently asked questions
- How is age calculated?
- As the calendar difference between your date of birth and today: full years, then remaining full months, then remaining days — the same way official documents count age.
- Does it handle leap years?
- Yes — the calculation uses real calendar dates, so February 29 birthdays and leap years are handled correctly.
