Problem: I have a taxonomy that includes terms for each day of the week. I would like to filter posts in a View using the current day of the week, so that only posts tagged with the term for today are shown.

Solution: Taxonomy term filters do not allow any date criteria in wp-admin, so custom code is required. Assuming the term slugs are "monday", "tuesday", and so on through "sunday", add the following code in your child theme's functions.php file to filter a View by term based on the local current day of the week:

add_filter( 'wpv_filter_query', 'only_todays_posts',99,3 );
function only_todays_posts( $query_args,$views_settings, $view_id) {
  if ($view_id == 12345){
    $query_args = array(
      'tax_query' => array(
        array(
          'taxonomy' => 'day-of-the-week',
          'field'   => 'slug',
          'terms' => strtolower(date('l')),
          'operator' => 'IN'
        ),
      ),
    );
  }
  return $query_args;
}

Replace 12345 with the numeric ID of your View, and replace day-of-the-week with the slug of your custom taxonomy. Nothing extra is needed in wp-admin.
