title: Find the difference between two dates (Inclusive of start and end date) in Java
body: <p>I need to find the difference between two dates in Java and the difference should be inclusive of start and end date. I tried using below piece of code but it is not including start and end date.</p>
  
  <pre><code>long diffDays = Days.daysBetween(new DateTime(startDate), new DateTime(endDate)).getDays();
  </code></pre>
  
  <p>Is there any utility method to achieve this?</p>
