title: Figure out the last day (in LocalDate) of a YearMonth instance - joda library
body: <p>I have a <code>YearMonth</code> instance, is there an easy way to figure what the last day, in <code>LocalDate</code>, of that instance is?</p>
  
  <p>I know there is a <code>toLocalDate(int day)</code>, but I may not know if the month has the 31st day or not.
  Of course, I can always put the code in a try-catch block and try with <code>31</code> first then if that fails, try with <code>30</code> (or <code>29</code>, or <code>28</code> for Feb).</p>
  
  <p>Is there a cleaner way?</p>
