I want jQuery or javascript age calculator, set the age of a user when their birthday is selected, I want do show from her age that a few days and months and years last.

For example:

user birthday is : 29/04/2010
The result should be like this: 2 years, 4 months, 5 days old.

What should be the best way to do this by jQuery or javascript?

function calAge()

    var curday = $("#curDay").val();
    var curmon = $("#curMonth").val();

    // $("#r8").val(secondsleft + " seconds");


    var as = parseInt(calyear) + dife.years + 1;

    var diff = Date.UTC(as, calmon - 1, calday, 0, 0, 0) - Date.UTC(curyear, curmon - 1, curday, 0, 0, 0);
    var datee = diff / 1000 / 60 / 60 / 24;


    if ((curday == calday) && (curmon == calmon))
    {
        $(".your_birthday span").html("Happy Birthday");
    } else
    {
        $(".your_birthday span").html(datee + " days left until your next birthday");
    }

    return true;



}
