我有两个变量

date1 = Mon Nov 25 2013 00:00:00 GMT+0530 (IST)
date2 = Mon Nov 25 2013 14:13:55 GMT+0530 (IST)

当我比较我得到的两个日期date2更大,我需要的是正确的.但我不想查看我所拥有的两个日期的时间部分.如何从这两个日期单独获取日期部分并进行比较？

var today = new Date();     //Mon Nov 25 2013 14:13:55 GMT+0530 (IST) 
d = new Date(my_value);     //Mon Nov 25 2013 00:00:00 GMT+0530 (IST) 
if(d>=today){               //I need to check the date parts alone.
    alert(d is greater than or equal to current date);
}
