Answer 1

The main reason is why ng-if is inside ng-repeat .

So if you try with only limitTo it will not work.

First you have to filter record based on your desired date and than you have to apply limitTo to ng-repeat .

Solution - ng-repeat="list in checkDate | filter: {day: '20200120'} | limitTo:3"

Answer 2

It's because ng-if is applied after limitTo filter producing result. In this case, use filter instead of ng-if directive. For example,

   <div ng-repeat="list in checkDate | filter: {day: '20200120'} | limitTo:3">
       <span>{{list.time}} {{list.day}}</span>
   </div>
