About the age calculator

How it works

Enter your date of birth to see your exact age in years, months and days, plus totals in weeks, hours, minutes and seconds, updated live. It also counts down to your next birthday.

Accurate to the calendar

Months and leap years are handled using real calendar dates rather than fixed 30-day months, so the result matches what you would count on a calendar.

Fun fact

You turn 10,000 days old at about 27 years and 4 months, and a billion seconds old at about 31 years and 8 months.
