how i show data on index page?

Answer 1

You need a view model to render your data. Instead of

return array('calendars' => $calendars);

You want this for a View:

$viewModel  =   new ViewModel
                    (
                        array
                        (
                            'calendars' =>  $calendars,
                        )
                    );

return $viewModel;

or this for Json:

$jsonModel  =   new JsonModel
            (
            array
            (
                'calendars' =>  $calendars,
                            )
            );

return $jsonModel;

make sure to add the use statements for your controller:

use Zend\View\Model\ViewModel;
use Zend\View\Model\JsonModel;

If you want to specify a specific view you can use:

$viewModel->setTemplate('path/to/specific/view.phtml');

or

$viewModel->setTemplate('mapping/for/specifc/view');

with the mapping specified in your module config
