title: How to get Weeks as a negative number in JodaTime?
body: <p>This is the current code am working with : </p>
  
  <pre><code> int weeks = Weeks.weeksBetween(movieReleaseDate, new DateTime()).getWeeks();
  </code></pre>
  
  <p>If the movie was released 8 weeks ago, it gives me the correct output as 8. 
  How do I make it return -8 ? To return a negative weeks seems to be the simplest hack which I do not want to do. </p>
