I have this code:
Empty Angular App
{{\"2015-07-08T15:10:
As you told, use javascript is better option.
var app = angular.module('my-app', []);
app.controller("my-controller", function($scope) {
$scope.name = "world";
$scope.mydate = new Date("2015-07-08T15:10:10.530Z");
var numberOfDaysToAdd = 46;
$scope.newdate = $scope.mydate.setDate($scope.mydate.getDate() + numberOfDaysToAdd);
});
