not save bootstrap date value to tha DB table

using bootstrap date picker in My form to save date value in the controller

 public function store(Request $request)
    {
       

        $task = new Task;
        $task->task_name   = $request->input('name');
        $task->body = $request->input('body');
        $task->assign          = $request->input('status');
        $task->priority        = $request->input('status');
        $task->duedate  = $request->input('date');
        $task->save();
        
    }

 <div class="col-xs-3">
       <div class="input-group">
        <div class="input-group-addon">
         <i class="fa fa-calendar">
         </i>
        </div>
        <input class="form-control" id="date" name="date" placeholder="MM/DD/YYYY" type="text"/>
       </div>
      </div>
