 First, I need to download the [Date](http://drupal.org/project/date "Date module on Drupal.org") module, and make my module dependent on date_popup by adding the following line into my module's .info file.
 
-    dependencies[] = date_popup
+        dependencies[] = date_popup
 
 Within my form builder function:
 
 ~~~php
 $form['date'] = array(
-  '#title' => t('Arrival date'),
+    '#title' => t('Arrival date'),
 
-  // Provided by the date_popup module
-  '#type' => 'date_popup',
+    // Provided by the date_popup module
+    '#type' => 'date_popup',
 
-  // Uses the PHP date() format - http://php.net/manual/en/function.date.php
-  '#date_format' => 'j F Y',
+    // Uses the PHP date() format - http://php.net/manual/en/function.date.php
+    '#date_format' => 'j F Y',
 
-  // Limits the year range to the next two upcoming years
-  '#date_year_range' => '0:+2',
+    // Limits the year range to the next two upcoming years
+    '#date_year_range' => '0:+2',
 
-  // Default value must be in 'Y-m-d' format.
-  '#default_value' => date('Y-m-d', time()),
+    // Default value must be in 'Y-m-d' format.
+    '#default_value' => date('Y-m-d', time()),
 );
