How do I calculate my exact age?

Your exact age is the difference between your date of birth and today's date, expressed in years, months, and days. Our calculator handles month-length differences and leap years automatically.

How many days old am I?

Multiply your age in years by 365.25 (accounting for leap years) and add the days since your last birthday. Our age calculator shows your exact age in total days.
