Calculator
Enter two birth dates to see the exact gap between them, in years, months, and days — plus which of the two is older.
Two people born in different years can still be less than a year apart in age, or more than one calendar year apart, depending on where their birthdays fall relative to each other. This tool works out the precise gap in years, months, and days between the two birth dates directly, rather than relying on the calendar-year difference alone.
Curious about a specific age milestone for either person? The full Age Calculator gives an exact age as of today or any other date.
