title: date_format not validating in Laravel
body: <p>I am using this validation for dates:</p>
  
  <pre><code>'fiscal_end' =&gt; 'required|date_format:dd/mm/yyyy'
  </code></pre>
  
  <p>Doing:</p>
  
  <pre><code>print_r(Input::all());
  die();
  </code></pre>
  
  <p>I get:</p>
  
  <pre><code>[fiscal_end] =&gt; 25/01/2017 
  </code></pre>
  
  <p>I don't understand what's wrong here that generates the error: Date needs to be in proper format dd/mm/yyyy.</p>
  
  <p>I am using Laravel 5.3 and datefield on form is actually Bootstrap Datepicker field.</p>
