Age Calculator
Enter your date of birth below to calculate your exact age, total days lived, total weeks lived, days until your next birthday, and the day of the week you were born.
How Age Is Calculated
Age is calculated by comparing your date of birth to the current date (or a date you specify). The calculation accounts for leap years correctly — each year is evaluated individually to determine whether it has 365 or 366 days. The exact breakdown into years, months, and days follows calendar math: the difference in years between the two dates adjusted for whether the month and day of the birth date have been reached in the target year.
