（Wordpress Multisite）在所选工作日显示页面作为主页

Question

How can I make chosen page to display as homepage of my multisite site depending on a week day? I have this function to display my page depending if user is logged in or not, next I want it to work differently during tuesday (picking different pages as follows):

function switch_homepage() {
    if ( is_main_site() ) {
        // Do stuff only for the main site
        if ( is_user_logged_in() ) {
            $page = 4284; // for logged in users
            update_option( 'page_on_front', $page );
            update_option( 'show_on_front', 'page' );
        } else {
            $page = 4133; // for logged out users
            update_option( 'page_on_front', $page );
            update_option( 'show_on_front', 'page' );
    }
    }
}

You can do something like this:

$today = date('l');

if ($today == 'Tuesday') {
    // your update_option() goes here
}
