title: Calendar.setFirstDayOfWeek does not work
body: <p>I want to get the week of the month for a specified date. For example for today(Sunday Sep 14 2014), the result should be 2. For tomorrow(Monday Sep 15 2014), result should be 3.</p>
  
  <p>So i do this :</p>
  
  <pre><code>Calendar cal = Calendar.getInstance();
  cal.setFirstDayOfWeek(Calendar.MONDAY);
  cal.setTime(myDate); // myDate is a Date object with the specified date
  cal.get(Calendar.WEEK_OF_MONTH);
  </code></pre>
  
  <p>But this gives me the result 3 for today and tomorrow. What am i doing wrong?</p>
