How your age is calculated
Your exact age is the time that has passed between your date of birth and today. This sounds simple, but months have different lengths and leap years add an extra day, so a quick subtraction often gives the wrong answer. This tool handles all of that for you.
Just pick your date of birth and the calculator returns your age in whole years, months, and days, plus the total number of days you have been alive. It is handy for forms, eligibility checks, and birthdays.
