<div class="form-group{{ $errors->has('day1') ? ' has-error' : '' }}">
                        <label for="day1" class="col-md-4 control-label">Day 1</label>

                        <div class="col-md-6">
                           <div class='input-group date' id='day1'>
                              <input type='text' class="form-control" name="day1" value="0" readonly="readonly" />
                                <span class="input-group-addon">
                                    <span class="glyphicon glyphicon-calendar">

                                </span>
                            </div>
                        </div>
                    </div>

Well, as I understand, you have different input fields and you want only those that have values != 0. You can use this pseudo code which traverses thru all input fields and your code will execute only if value != 0:

$('input').each(function() {
  if ($(this).val() != 0) {
    // code goes here...
  }
});

$('input').on('change', function() {
  updateCount();
})

function updateCount() {
  var count = 0;
  $("input:not('.k-textbox')").each(function() {
    if ($(this).val() != 0) {
      count++;
    }
  });
  $(".k-textbox").val(count + 'x');
  console.log(count + 'x');
}

      <input type='text' name='total[]' id='total2' value='0' />

    <td>
      <input type='text' name='total[]' id='total4' value='0' />
    </td>
  </tr>

      <input type="text" class="k-textbox" value="" style="color: red; text-align: right; font-family: courier" name="total_amt_due" id="amt_due" readonly="readonly" />
    </td>
