function getAge(dateString) {
    var today = new Date();
    var birthDate = new Date(dateString);
    var age = today.getFullYear() - birthDate.getFullYear();
    var m = today.getMonth() - birthDate.getMonth();
    if (m < 0 || (m === 0 && today.getDate() < birthDate.getDate())) {
        age--;
    }
    return age;
}

alert(getAge("09/23/1981"));

This is from: http://stackoverflow.com/questions/4060004/calculate-age-in-javascript

Simply pass the getAge function the users birthday and whala!
