How to display most read posts in the last week?

Hello,
How to display most read posts in the last week?

I have the following code to record every hit of the posts, so i would know how many people read the post.

function getPostViews($postID){
    $count_key = 'post_views_count';
    $count = get_post_meta($postID, $count_key, true);
    if($count==''){
        delete_post_meta($postID, $count_key);
        add_post_meta($postID, $count_key, '0');
        return "0 View";
    }
    return $count.' Views';
}
function setPostViews($postID) {
    $count_key = 'post_views_count';
    $count = get_post_meta($postID, $count_key, true);
    if($count==''){
        $count = 0;
        delete_post_meta($postID, $count_key);
        add_post_meta($postID, $count_key, '0');
    }else{
        $count++;
        update_post_meta($postID, $count_key, $count);
    }
}
// Remove issues with prefetching adding extra views
remove_action( 'wp_head', 'adjacent_posts_rel_link_wp_head', 10, 0);
/**
 * Add a new column in the wp-admin posts list
 *
 * @param $defaults
 *
 * @return mixed
 */
function subh_posts_column_views( $defaults ) {
 $defaults['post_views'] = __( 'Views' );

 return $defaults;
}

/**
 * Display the number of views for each posts
 *
 * @param $column_name
 * @param $id
 *
 * @return void simply echo out the number of views
 */
function subh_posts_custom_column_views( $column_name, $id ) {
 if ( $column_name === 'post_views' ) {
 echo getPostViews( get_the_ID() );
 }
}
add_filter( 'manage_posts_columns', 'subh_posts_column_views' );
add_action( 'manage_posts_custom_column', 'subh_posts_custom_column_views', 5, 2 );

How can i set the following

$options = array(
			'post_type' => 'post',
			'post_status' => 'publish',
			'posts_per_page' => $limit,
			'ignore_sticky_posts' => true,
			/* 'orderby' => 'meta_value_num', */
			'orderby' => 'rand',
			'order' => 'desc',
			'meta_key' => 'post_views_count'
		);

to show most read posts in the last week?
