4-4-5 calendar extra week every 5/6 years

4-4-5 calendar is 364 days (7days - 52 weeks) not 365. Every 6 years 4-4-5 month starting 1 week earlier then calendar month. In our  4-4-5 calendars JAN-2030  will start on  November 26, 2029.

What is the best way to compensate this date shift? Usually every 5/6 years people adding extra week in December and last quarter is 4/4/6. But Oracle is not supporting it in manufacturing calendars.
