Events post type

Events is created as a custom post type in wp?what would be the slug for events post type.

<?php$args = array(
	'public'   => true,
	'_builtin' => false
);?>
 <?php $show_post_types = get_post_types($args); ?>

  print_r($show_post_types); 

This code should show the custom post types in WP built by user or by a plugin.And the result was empty.

I need to get the events created by a user. This is to be displayed in user listing(profile builder pro)
