java.util.Date now = new Date();
 
java.util.Date fourDaysAgo = 
    new Date(now.getTime() - (1000 * 60 * 60 * 24 * 4));
 
java.text.SimpleDateFormat dtFormat = 
    new java.text.SimpleDateFormat("yyyy-MM-dd");
 
System.out.println("Today is: " + dtFormat.format(now));
System.out.println("Four days ago was: " + dtFormat.format(fourDaysAgo));

    GregorianCalendar gc = new GregorianCalendar(2004, 5, 28);
    gc.add(Calendar.DAY_OF_MONTH, -4);

Using the GregorianCalendar class, you don't need to go into the mathematical calculations.

Hope this helps.
