How to Calculate Age

Exact age: 12,775 days = 1,825 weeks = 35 years

Methodology

Calculating age isn't simply subtracting birth year from current year. The number of days in months varies (28, 30, or 31), and leap years occur every 4 years (adding a 29th day to February).

Leap Years

A year is a leap year if divisible by 4, except century years must be divisible by 400. This calculator automatically accounts for leap days.
