+For **calendar modules** it's up to you if you want to show the tags of an event in the calendar. To do so, you need to modify the default calendar template `cal_default` or you create your own `cal_default` based template. To show the tags you can access the `tags` or `taglist` fields of the respective events, e.g.
+
+```php
+          <?php foreach ($day['events'] as $event): ?>
+            <div class="event cal_<?= $event['parent'] ?><?= $event['class'] ?>">
+              <a href="<?= $event['href'] ?>" title="<?= $event['title'] ?> (<?php if ($event['day']) echo $event['day'] . ', '; ?><?= $event['date'] ?><?php if ($event['time']) echo ', ' .  $event['time']; ?>)"<?= $event['target'] ?>><?= $event['link'] ?></a>
+              <div>
+              	<?php foreach ($event['taglist'] as $tagdata): ?>
+              		<div class="<?= $tagdata['class'] ?>"><?= $tagdata['url'] ?></div>
+              	<?php endforeach; ?>
+              </div>
+            </div>
+          <?php endforeach; ?>
+```
+
+The `tags` field contains an array with all available tags for an event, e.g.
+
+```php
+Array(
+  [0] => conference
+  [1] => meeting
+)
+```
+
+The `taglist` field contains an array of arrays which contain the URL for the tag, the tag name and the tag class, e.g.
+
+```php
+Array(
+  [0] => Array(
+    [url] => <a href=".../tags/conference.html">conference</a>
+    [tag] => conference
+    [class] => conference
+  )
+  [1] => Array(
+    [url] => <a href=".../tags/meeting.html">meeting</a>
+    [tag] => meeting
+    [class] => meeting
+  )
+)
+```

 ## Content elements
 
 The tags extension extends the Contao content element Heading and introduces an additional parameter Show with tags only into the expert settings. If you check this option Contao only shows the heading if one or more tags are used on the content page, e.g. if the page was opened from a tag cloud.
