Age Calculator
Your exact age in years, months and days
Enter your date of birth to get your exact age — down to the day — plus the total number of days and weeks you've been alive.
How age is calculated
We compare your birth date to today, accounting for months of different lengths and leap years, to give your precise age in years, months and days. Change the date to find anyone's age, or the age on a past or future birthday.
