Once you have your spec down more precisely, look perhaps to the 'java.util.Calendar' class for ways to implement it. It will require piecemeal assembly of the exact algorithm you want, using things like
<http://docs.oracle.com/javase/7/docs/api/java/util/Calendar.html#get(int)>
<http://docs.oracle.com/javase/7/docs/api/java/util/Calendar.html#WEEK_OF_YEAR>
<http://docs.oracle.com/javase/7/docs/api/java/util/Calendar.html#add(int, int)>
<http://docs.oracle.com/javase/7/docs/api/java/util/Calendar.html#setFirstDayOfWeek(int)>
<http://docs.oracle.com/javase/7/docs/api/java/util/Calendar.html#setMinimalDaysInFirstWeek(int)>
etc.

If all that is too primitive, the Joda Time initiative is very promising:
