Create a custom event post

The easiest way to create a custom post type in WordPress is by using a plugin. This method is recommended for beginner because it is safe and easy.

For example :
Custom Post Type UI

The problem with using a plugin is that your custom post types will disappear when the plugin is deactivated.
you can manually create your custom post type by adding the required code in your theme’s functions.php file.

// Our custom post type function
function create_posttype() {

    register_post_type( 'events',
    // CPT Options
        array(
            'labels' => array(
                'name' => __( 'Event' ),
                'singular_name' => __( 'Event' )
            ),
            'public' => true,
            'has_archive' => true,
            'rewrite' => array('slug' => 'events'),
        )
    );
}
// Hooking up our function to theme setup
add_action( 'init', 'create_posttype' );

It registers a post type ‘events’ with an array of arguments. These arguments are the options of custom post type. This array has two parts, the first part is labels, which itself is an array. The second part contains other arguments like public visibility, has archive, and slug.
