body: <p>When I try to format my <code>$date</code> to <code>d/m/Y</code> it's work fine </p>
  
  <pre><code>$date = '20/4/2015';
  Carbon::createFromFormat('d/m/Y', $date)
  </code></pre>
  
  <p>But when I try to format my <code>$date</code> to <code>d/M/Y</code></p>
  
  <pre><code>$date = '20/4/2015';
  Carbon::createFromFormat('d/M/Y', $date)
  </code></pre>
  
  <p>I got an error like the following,</p>
  
  <blockquote>
    <p>The separation symbol could not be found Trailing data</p>
  </blockquote>
