        return {
            getDateToString: function (date, format) {
                if (angular.isDate(date) && angular.isString(format)) {
                    return $filter("date")(date, format);
                }
            },
            getStringToDate: function (string) {
                if (angular.isString(string)) {
                    return new Date(string.replace(/-/g, "/"));
                }
            }
        };
