How can I get the last 5 element of this tax query?

Question

$args = array(
'post_type' => 'news',
'posts_per_page' => 5,
'post_status' => 'publish',
'order' => 'ASC',
'tax_query' => array(
    array(
        'taxonomy' => 'week',
        'field' => 'slug',
        'terms' => $currweeknumber,
    )
)
);
$post = get_posts($args);

I have a page which posts 5 news each week. I have a problem. A year passed since I started my blog and this $args query shows me the last year news, not the actual. This is because week number doesn't changed at all, it's the same value from 1 to 52 (basically I have 52 terms with the value of 1,2,3...etc). Is there any way to get the last 5 element of this array, not the first 5? I'm tried with 'order' => ''DESC' but not worked.

Answer 1

add the 'date_query' parameter to your query and include the current year.

$args = array(
  'post_type' => 'news',
  'posts_per_page' => 5,
  'post_status' => 'publish',
  'order' => 'ASC',
  'tax_query' => array(
     array(
      'taxonomy' => 'week',
      'field' => 'slug',
      'terms' => date("W", strtotime("this week")),
    )
  ),
  'date_query' => array(
    array(
      'year'  => date("Y")
    )
  )
);
