Enter a date of birth to see the age.

Find your exact age in years, months and days from a date of birth, as of today or any other date. You also get the total months, weeks and days, the weekday you were born on and a countdown to your next birthday. Leap years and 29 February births are handled. Nothing is stored or sent.

How to calculate your age

1. Enter the date of birth.
2. Leave the second date on today to get the current age, or pick another date to see the age on that day.
3. Read the exact age and the extra figures: total months, weeks and days, the weekday of birth and the countdown to the next birthday.

Why calculate an exact age?

Forms, schools, sports categories, insurance and visa applications often ask for an exact age on a given date, and counting by hand across months of different lengths and leap years is easy to get wrong. A calculator answers in a second and also tells you how many days old you are and how many days remain until your next birthday.
