title: Number of days between two dates in Joda-Time
body: <p>How do I find the difference in Days between two <a href="http://www.joda.org/joda-time/" rel="noreferrer">Joda-Time</a> <a href="http://www.joda.org/joda-time/apidocs/org/joda/time/DateTime.html" rel="noreferrer"><code>DateTime</code></a> instances?
  With ‘difference in days’ I mean if start is on Monday and end is on Tuesday I expect a return value of 1 regardless of the hour/minute/seconds of the start and end dates.</p>
  
  <p><code>Days.daysBetween(start, end).getDays()</code> gives me 0 if start is in the evening and end in the morning.</p>
  
  <p>I'm also having the same issue with other date fields so I was hoping there would be a generic way to 'ignore' the fields of lesser significance. </p>
  
  <p>In other words, the months between Feb and 4 March would also be 1, as would the hours between 14:45 and 15:12 be. However the hour difference between 14:01 and 14:55 would be 0.</p>
