+First, I need to download the <a href="http://drupal.org/project/date" title="Date module on Drupal.org">Date</a> module, and make my module dependent on date_popup by adding the following line into my module's .info file.
+
+    dependencies[] = date_popup
+
+Within my form builder function:
+
+~~~php
+$form['date'] = array(
+  '#title' => t('Arrival date'),
+
+  // 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',
+
+  // 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()),
+);
+~~~
