Age Calculator

Calculate exact age in years, months, and days between any two dates.

Date of birth

As of date

How it works

Enter a birth date and, optionally, a different 'as of' date, and this tool works out the exact difference in years, months, and days — along with the total number of days between the two dates.

Because it accounts for varying month lengths and leap years properly rather than doing simple rounding, it stays accurate for calculating age as of any specific date, not just today.
