Age Calculator
Calculate your exact age in years, months, and days — plus days until your next birthday.
How age is calculated
Age is calculated by counting the number of complete years, months, and days between your birth date and today (or a date you specify). Leap years and varying month lengths are handled correctly.
This calculator uses calendar age — the standard way birthdays are counted, where you turn a year older on the anniversary of your birth date.
