title: How to set day of the week in Bulgarian language
body: <p>I have to show tomorrow's day of the week in Bulgarian.<br>
  It is shown in English, how do I set it in Bulgarian?</p>
  
  <pre><code>&lt;?php
   $now= new DateTime('now');
   $date=$now-&gt;modify('+1 day');                    
  
   echo $date-&gt;format('l');
            //prints Saturday          
  </code></pre>
  
  <p>I did this with an array of Bulgarian names of days and it works, but is there a way to do it with <code>setlocale</code> or something else?</p>
