How to subtract two angularjs date variables

Question

I am fairly new to angularjs, but here it goes. I am able two dates through angularjs in the form dd/mm/yyyy, but what I need to do is somehow subtract the two

Answer 1

I tried the below one and it worked out for me

var selecteddate = new Date($rootscope.selectvalue);
$scope.firstDate = selecteddate .getTime();
$scope.SecondDate = new Date().getTime();

selected date is the one which is selected from calender and it is coming from parent scope. second date will be today's date. later i will find difference using moment diff.

var differenceinDays=parseInt(
      moment.duration(
        moment($scope.firstDate).diff(
          moment($scope.SecondDate)
        )
      ).asDays()
    );

I am using parseInt because i want to return the integer value only

Hope this works
