Activate and deactivate plugin automatically

I like the idea of running this through a schedule event in WordPress, https://codex.wordpress.org/Function_Reference/wp_schedule_event

Here is a snippet that hopefully will get you there:

<?php
  
  if(!wp_next_scheduled('daily_plugin_check')){
    wp_schedule_event( time(), 'daily', 'daily_plugin_check' );
  }

  add_action( 'daily_plugin_check', 'toggle_plugins' );

  function toggle_plugins() {
    switch(date('D')){
      case 'Mon' :
      case 'Wed' :
      case 'Fri' :
        // Could be an array or a single string
        $plugin_to_activate = 'akismet/akismet.php';
        $plugin_to_deactivate = 'akismet/akismet.php';
        break;
      // Continue with each day you'd like to activate / deactive them
    }

    if(!function_exists('activate_plugin')){
      require_once ABSPATH . 'wp-admin/includes/plugin.php';
    }

    if(!empty($plugin_to_activate){
      // If $plugin_to_activate is an array, then you can foreach of it
      if(!is_plugin_active($plugin_to_activate)){
        activate_plugin($plugin_to_activate);
      }
    }

    if(!empty($plugin_to_deactivate){
      // If $plugin_to_activate is an array, then you can foreach of it
      if(is_plugin_active($plugin_to_deactivate)){
        deactivate_plugins($plugin_to_deactivate);
      }
    }

  }

Hope that helps!

You can mange this by adding the following to your functions.php file.

Checking todays timestamp for the days you want the plugin active - on the off days the plugin is disabled.

$timestamp = time(); // Timestamp
$day       = date( 'D', $timestamp ); // Get day from timestamp
$active    = array( 'Mon', 'Wed', 'Fri', 'Sat' ); // Days plugin to be active
if ( in_array( $day, $active, true ) ) { // Yoast SEO is active
    activate_plugin( '/wordpress-seo/wp-seo.php' );
} else { // Yoast SEO is deactivated
    deactivate_plugins( '/wordpress-seo/wp-seo.php' );
}

It uses activate_plugin() to activate and deactivate_plugins() to deactivate the plugin.
