title: Get last Sunday in Month - JavaScript
body: <p>I'm from Europe and there we have the summertime. It is +1 hour every date between two dates.
  These dates are the last Saturday of March and the last of oktober. I'm trying to make my program automatic realize the summertime. And for that I have to get the last Sunday of a month.</p>
  <p>I found this: <a href="https://stackoverflow.com/questions/29026602/java-last-sunday-of-a-month">java last sunday of a month</a> but I was not able to translate it into JavaScript.</p>
