Well, since you are going to have three input fields instead of one, the task is just to apply the mask to three textboxes instead of to one, and then constructing the argument to the timeago method call. The rest would be unchanged. Something like this:

$('input[name="DAY"]').mask("99");
$('input[name="MONTH"]').mask("99");
$('input[name="YEAR"]').mask("9999");
$('.deleteCookie').click(function() {
    $.cookie('age', null);
});
$('.submit').click(function() {
    var enteredDOB = $('input[name="DAY"]').val() + "/" +               
                     $('input[name="MONTH"]').val() + "/" +
                     $('input[name="YEAR"]').val();
    var age = jQuery.timeago(enteredDOB);
    if (age === 'NaN years ago') {
        alert('DOB must be valid');
    } else {
        $.cookie('age', age);
        if (parseInt(age, 10) >= 21) {
            alert('you\'re of age');
        } else {
            alert('you\'re too young');
        }
    }
});

if (null !== $.cookie('age')) {
    alert('saved Cookie ' + $.cookie('age'));
}

With regards to the "remember me" functionality, it is just a question of reading the age cookie upon page load, and redirecting to the next page if the age cookie contains a valid value, although this would probably be a check better done server-side.
