title: How do I obtain the number of days within a given month using Joda-Time?
body: <pre><code>30 days hath September,
     April, June and November,
   All the rest have 31,
     Excepting February alone
  (And that has 28 days clear,
     With 29 in each leap year).
  </code></pre>
  
  <p>Can I obtain this info anagrammatically?
  (I don't mean the poem, of course)</p>
