How to render a block in php for a special node id
Add this to your theme's template.php file:

function THEME_block_view_alter(&amp;$data, $block) {
  if ($block-&gt;module == 'opening_hours' &amp;&amp; $block-&gt;delta == 'week') {
    $node_fixed = node_load(77); // swap out 77 for your node's id
    if ($node_fixed) {
      $data['content']['#node'] = $node_fixed;
    }
  }
}
