Year Shortcode for Copyright in WordPress Blog

Because lately more and more SEO pleople sustain how important is the Copyright and the year at the bottom of the page, here is a simple way to generate the year automatically in order to not need to change it manually each year.

Add the following code to the functions.php file:

function year_shortcode() {
  $year = date('Y');
  return $year;
}
add_shortcode('year', 'year_shortcode');

Use [year] in your posts.
