Compare two Dates using Javascript

Before we begin this tutorial you might like to check on this.

In the below example I have two date objects. I am using the .getTime() method of the date object to compare these dates and show an alert accordingly.

var firstDate = new Date("2/12/2012");  
var secondDate = new Date("2/12/2012");

// We can use all comparison operators like '=', or less than, greater than operators.  
if (firstDate.getTime() == secondDate.getTime()) {  
alert("Both dates are same.");  
}  
else {  
alert("Different dates.");

}
