let me know if have further questions. many in advance

in response first answer created module:

 app.filter("dayfilter",[         function () {             return function dayfilter(items,date) {                 var d = new date();                 var filtereditems = [];                 var begin, end                 begin = d.sethours(0, 0, 0);                 end = d.sethours(23, 59, 59);                 angular.foreach(items, function(item) {                     if (item > begin && item < end) {                         filtered.push(item);                     }                 })                 console.log("filtered day", d);                 return filtereditems             }             $filter("dayfilter");             // dayfilter(new date(),'date');         }]);   no longer error, snapshots not appear in output, though following in console: iltered day thu nov 10 2016 23:59:59 gmt-0500 (cot) main.js?v=2016-11-08-3:89 filtered day thu nov 10 2016 23:59:59 gmt-0500 (cot) main.js?v=2016-11-08-3:89 filtered day thu nov 10 2016 23:59:59 gmt-0500 (cot) main.js?v=2016-11-08-3:89 filtered day thu nov 10 2016 23:59:59 gmt-0500 (cot) main.js?v=2016-11-08-3:89 filtered day thu nov 10 2016 23:59:59 gmt-0500 (cot) main.js?v=2016-11-08-3:89 filtered day thu nov 10 2016 23:59:59 gmt-0500 (cot) main.js?v=2016-11-08-3:89 filtered day thu nov 10 2016 23:59:59 gmt-0500 (cot) main.js?v=2016-11-08-3:89 filtered day thu nov 10 2016 23:59:59 gmt-0500 (cot) main.js?v=2016-11-08-3:89 filtered day thu nov 10 2016 23:59:59 gmt-0500 (cot) 

the template using dayfilter in ng-repeat directive. add filter module, use module.filter method:

app.filter("dayfilter", () => {    return function dayfilter(items, date) {        //filter code        return filtereditems;    }; }); 

to instantiate filter in controller, use $filter service:

$filter("dayfilter");
