Determining Date Equality in Javascript

I need to find out if two dates the user selects are the same in Javascript. The dates are passed to this function in a String ("xx/xx/xxxx").That is all the granularity I need.

Here is my code:

		var valid = true;
	var d1 = new Date($('#datein').val());
	var d2 = new Date($('#dateout').val());
	alert(d1+"\n"+d2);
	if(d1 > d2) {
		alert("Your check out date must be after your check in date.");
		valid = false;
	} else if(d1 == d2) {
		alert("You cannot check out on the same day you check in.");
		valid = false;
	}

The javascript alert after converting the dates to objects looks like this:

Tue Jan 25 2011 00:00:00 GMT-0800 (Pacific Standard Time)

Tue Jan 25 2011 00:00:00 GMT-0800 (Pacific Standard Time)

The test to determine if date 1 is greater than date 2 works. But using the == or === operators do not change valid to false.

Use the getTime() method. It will check the numeric value of the date and it will work for both the greater than/less than checks as well as the equals checks.

EDIT:

if (d1.getTime() === d2.getTime())

If you don't want to call getTime() just try this:

(a >= b && a <= b)

var d1 = new Date($('#datein').val());
var d2 = new Date($('#dateout').val());

use two simple ways to check equality

1. if( d1.toString() === d2.toString())
2. if( +d1 === +d2)

var date = Wed Oct 07 2015 19:48:08 GMT+0200 (Central European Daylight Time);

var dateOne = new Date(date);
var dateTwo = new Date();

var isEqual = dateOne.getDate() === dateTwo.getDate()

this will give you the dates equality
