About the Age Calculator
The Age Calculator works out an exact age from a date of birth to any reference date, broken down into years, months and days, plus the total number of days lived. It handles leap years correctly, so the result is the real figure rather than a rough estimate.
Frequently asked questions
Yes. The calculation steps through real calendar months and days, so February 29ths are counted correctly and the years/months/days breakdown matches the actual calendar.
