	var cur = new Date();
	var diff = cur-birthdate; // This is the difference in milliseconds
	var age = Math.floor(diff/31557600000); // Divide by 1000*60*60*24*365.25
     var month=;//i want to calcuate this using millsecond only
     var days=;//i want to calcuate this using millsecond only

从分组的其余部分计算月数和不足

var remainder = diff % 31557600000;
var month = Math.floor(remainder / (1000*60*60*24*30.5));
var remainder2 = remainder % (1000*60*60*24*30.5);
var days = Math.floor(remainder2 / (1000*60*60*24));

在javascript中使用毫秒计算月和日
