To use formatted date string instead of Date object as ng-model for Angular Datepicker, you need to create a wrapper directive. The wrapper directive will parse your string into Date object and pass it to the datepicker. When you select a date, it is converted from Date back into string. Here is an example (Plunker):

(function () {
    'use strict';

    angular
        .module('myExample', ['ngAnimate', 'ngSanitize', 'ui.bootstrap'])
        .controller('MyController', MyController)
        .directive('myDatepicker', myDatepickerDirective);

    MyController.$inject = ['$scope'];

    function MyController ($scope) {
      $scope.dateFormat = 'dd MMMM yyyy';
      $scope.myDate = '30 Jun 2017';
    }

    myDatepickerDirective.$inject = ['uibDateParser', '$filter'];

    function myDatepickerDirective (uibDateParser, $filter) {
        return {
            restrict: 'E',
            scope: {
                name: '@',
                dateFormat: '@',
                ngModel: '='
            },
            required: 'ngModel',
            link: function (scope) {

                var isString = angular.isString(scope.ngModel) && scope.dateFormat;

                if (isString) {
                    scope.internalModel = uibDateParser.parse(scope.ngModel, scope.dateFormat);
                } else {
                    scope.internalModel = scope.ngModel;
                }

                scope.open = function (event) {
                    event.preventDefault();
                    event.stopPropagation();
                    scope.isOpen = true;
                };

                scope.change = function () {
                    if (isString) {
                        scope.ngModel = $filter('date')(scope.internalModel, scope.dateFormat);
                    } else {
                        scope.ngModel = scope.internalModel;
                    }
                };

            },
            template: [
                '
',
                    '',
                    '',
                        '  ',
                    '',
                '
'
            ].join('')
        }
    }

})();

  
    
    
    
    
    
    
  

  
    

      

        Date format: {{dateFormat}}
      
      

        Value: {{myDate}}
