javascript - How to compare the date part alone from a date time value

I have two variables namely

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

When I compare the two dates I get that date2 is greater which I need is correct. But I do not want to check the time part of the two dates I have. How could I get the date part alone from these two dates and compare it?

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);
}

Try clearing the time using Date.setHours:

dateObj.setHours(hoursValue[, minutesValue[, secondsValue[, msValue]]])

Example Code:

var today = new Date();
today.setHours(0, 0, 0, 0);
d = new Date(my_value); 
d.setHours(0, 0, 0, 0);

if(d >= today){ 
    alert(d is greater than or equal to current date);
}
