Calendar week views block dates
First you need to copy calendar-week-overlap.tpl.php from calendar/theme to your custom Drupal theme and add the following lines:

Add this code before html code - after line 30

$start_date = date_format($view-&gt;date_info-&gt;min_date, 'U'); 


After line 40 &lt;th class="calendar-agenda-hour"&gt;&amp;nbsp;&lt;/th&gt; replace the following code

 &lt;?php foreach ($day_names as $cell): ?&gt;
    &lt;th class="&lt;?php print $cell['class']; ?&gt;" id="&lt;?php print $cell['header_id']; ?&gt;"&gt;
      &lt;?php print $cell['data']; ?&gt;
    &lt;/th&gt;
  &lt;?php endforeach; ?&gt;


with this code

&lt;?php $i = 0; foreach ($day_names as $cell): ?&gt;
    &lt;th class="&lt;?php print $cell['class']; ?&gt;" id="&lt;?php print $cell['header_id']; ?&gt;"&gt;
      &lt;?php print $cell['data']; ?&gt;, &lt;?php print date('d/m/Y', strtotime("+$i day", $start_date)); $i++ ?&gt;
    &lt;/th&gt;
  &lt;?php endforeach; ?&gt;
