title: NSDate Formatting individually
body: <p>I'm using NSDateFormatter to format NSDate variables like this:</p>
  
  <pre><code>NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init];
  dateFormatter.dateFormat = @"dd/MM";
  </code></pre>
  
  <p>I want to provide an unique format only for the first day of year(setDateFormat:@"dd/MM/yyyy").</p>
  
  <p>Is it possible?</p>
  
  <p>Thanks in advance.</p>
