var dayThen = parseInt(mdate.substring(8,10), 10);

var today = new Date();
var birthday = new Date(yearThen, monthThen-1, dayThen);

var differenceInMilisecond = today.valueOf() - birthday.valueOf();

var year_age = Math.floor(differenceInMilisecond / 31536000000);
var day_age = Math.floor((differenceInMilisecond % 31536000000) / 86400000);

if ((today.getMonth() == birthday.getMonth()) && (today.getDate() == birthday.getDate())) {
alert("Happy B'day!!!");
}

var month_age = Math.floor(day_age/30);

day_age = day_age % 30;

if (isNaN(year_age) || isNaN(month_age) || isNaN(day_age)) {
$("#exact_age").text("Invalid birthday - Please try again!");
}
