Add the following code to functions.php in a child theme. This adds the field ‘_my_date_ymd‘ to the custom fields drop down in the Divi display conditions.

Change +0 in strtotime(‘+0 day’) as needed

• +0 is today
• -1 is yesterday
• +1 is tomorrow

// START Add Global Dynamic date field to hide Booking widgets with a Divi Display Condition
function add_my_date_field($post_id) {
  // Only run on singular pages/posts
  if (!is_singular() || is_admin()) return;

  // Get the date in Ymd format
  $mydate = date('Ymd', strtotime('+0 day'));

  // Save as a custom field (temporary, per page load)
  update_post_meta($post_id, '_my_date_ymd', $mydate);
}
add_action('wp', function() {
  if (is_singular()) {
    add_my_date_field(get_the_ID());
  }
});
