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

Question

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

Answer 1

The best way would be to modify the accepted answer's if statement as follows

if(d.setHours(0,0,0,0) >= today.setHours(0,0,0,0))

In this way, you can easily check for equality as well because the return type for setHours() is integer.

Answer 2

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);
}

Answer 3

     var StartDate = $("#StartDate").val();

      var EndDate = $("#EndDate").val();

      if ((( EndDate - StartDate)/ (86400000*7))<0) 
      { 
       alert("Start Date Must Be Earlier Than End Date"); $("#StartDate").focus(); 
        error = true; 
        return false; 
      }

Answer 4

Try:

    var today = new Date();     //Mon Nov 25 2013 14:13:55 GMT+0530 (IST) 
    var d = new Date(my_value);     //Mon Nov 25 2013 00:00:00 GMT+0530 (IST) 
    var todayDateOnly = new Date(today.getFullYear(),today.getMonth(),today.getDate()); //This will write a Date with time set to 00:00:00 so you kind of have date only
    var dDateOnly = new Date(d.getFullYear(),d.getMonth(),d.getDate());

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