var d = new Date();

var today = new Date(1453094034000);
var birthday = new Date('December 17,1995');
var birthday = new Date('1995-12-17T03:24:00');
var birthday1 = new Date(1995,11,17,3,24,0);
birthday1.toLocaleString() // "1995/12/17 上午3:24:00"
// 注意: 0-11数字表示1-12月，var a = new Date(2006,5,6) 结果是2006-6-6
// 0-6 表示星期几

window.setInterval(function(){
