Answer 1

You can try this

Calendar now = Calendar.getInstance();


  now.set(Calendar.YEAR,2013);
  now.set(Calendar.MONTH,04);//0- january ..4-May
  now.set(Calendar.DATE, 04);

System.out.println("Current week of month is : " +
            now.get(Calendar.WEEK_OF_MONTH));

System.out.println("Current week of year is : " +
            now.get(Calendar.WEEK_OF_YEAR));

Answer 2

This should solve your problem with using this:

Calendar cal = Calendar.getInstance();
cal.setTime(date);
int weekOfYear = ca.get(Calendar.WEEK_OF_YEAR);
