How to change the date format using AngularJS ?

AngularJS provides two different ways to change the format of the date. It can be achieved by the following approaches:

Using HTML Template Binding
Using JavaScript

HTML Template Binding: In this method, we use pipe (|) operator. This pipe operator helps to convert a date object, number as per the required format (this includes – angular standard format and user-defined format). In angular, date objects can be modified based on any format, locale, and timezone using this operator. It formats a date in a readable format only.

Syntax:

{{ dateVariable | date [ : format [ : timezone [ : locale ] ] ] }}

Attributes Description:

Attribute	Description
Format	Both predefined as well as user defined formats can be used in this attribute. The default value of this parameter is – ‘mediumDate’. Optional Parameter
TimeZone	The default value of timezone is – user’s local system timezone. We can provide value as offset (‘0530’) or standard UTC/GMT (IST) or continental US timezone abbreviation. Optional Parameter
Locale	The default value for locale is – ‘undefined’. For example, we can set it as – ‘en_US’.Optional Parameter

Example: In this example, we are changing the current date into different formats. This date format includes the standard as well as user-defined formats.

<!DOCTYPE html> 
<html> 
  
<head> 
    <script src= 
"https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"> 
    </script> 
</head> 
  
<body> 
    <div ng-app="myApp" ng-controller="datCtrl"> 
        <p> 
            Formatted Date with default parameters: 
            {{ dateValue | date }} 
        </p> 
  
        <p> 
            Formatted Date with standard filter (ShortDate): 
            {{ dateValue | date:'shortDate' }} 
        </p> 
  
        <p> 
            Formatted Date with standard filter (FullDate): 
            {{ dateValue | date:'fullDate' }} 
        </p> 
  
        <p> 
            Formatted date with user defined format: 
            {{ dateValue | date : "'today is ' MMMM d, y" }} 
        </p> 
    </div> 
  
    <script> 
        var app = angular.module('myApp', []); 
        app.controller('datCtrl', function ($scope) { 
            $scope.dateValue = new Date(); 
        }); 
    </script> 
</body> 
  
</html> 

When we run the code, it will provide the current date in different formats.

Input Current Date: 24th March 2020

Output:

Formatted Date with default parameters: Mar 24, 2020 
Formatted Date with standard filter (ShortDate): 3/24/20
Formatted Date with standard filter (FullDate): Tuesday, March 24, 2020
Formatted date with user defined format:today is March 24, 2020

As we have seen that it is pretty easy to work with this pipe operator. Now we will take a look at the second approach.

Using JavaScript Controller: This approach is helpful if you have a date in string format.

Syntax:

$scope.dateVariable = $filter('date')("dateString", "dateformat");

Example: Here, we are using an angular controller to change the date format. The date is passed as a string and by using $filter filter, which is used to filter the object elements and array. It provides you the subset of an original array in the specified format.

</head> 
  
<body> 
    <div ng-app="MyApp"> 
        <div ng-controller="MyCtrl"> 
            Input Date in String Format: {{myDate}}<br> 
            Output Date : {{myDateFiltered}} 
        </div> 
    </div> 
  
    <script> 
        var app = angular.module('MyApp', []); 
  
        app.controller('MyCtrl', ['$scope', '$filter',  
                function ($scope, $filter) { 
            $scope.myDate = new Date('2013/07/21'); 
              
            $scope.myDateFiltered = $filter('date') 
                    ($scope.myDate, 'dd/MM/yy'); 
        }]); 
    </script> 
</body> 
  
</html> 

Output:

Input Date in String Format: "2013-07-20T18:30:00.000Z"
Output Date : 21/07/13
