Answer 1

use WEEK_OF_MONTH will be better, no cross year issue.

public static void main(String[] args) throws Exception {
  for (String m : new String[] { "2012-11", "2012-12", "2013-01", "2013-02", "2013-03",
              "2013-04", "2013-05", "2013-06" }) {
      SimpleDateFormat format = new SimpleDateFormat("yyyy-MM");
      Date date = format.parse(m);
      Calendar c = Calendar.getInstance();
      c.setTime(date);

      int start = c.get(Calendar.WEEK_OF_MONTH);

      c.add(Calendar.MONTH, 1);
      c.add(Calendar.DATE, -1);
      int end = c.get(Calendar.WEEK_OF_MONTH);
      System.out.println(" # of weeks in " + format.format(c.getTime())
              + ": " + (end - start + 1));
  }
}

results:

# of weeks in 2012-11: 5
# of weeks in 2012-12: 6
# of weeks in 2013-01: 5
# of weeks in 2013-02: 5
# of weeks in 2013-03: 6
# of weeks in 2013-04: 5
# of weeks in 2013-05: 5
# of weeks in 2013-06: 6
