Just a thought.
Hope this works for you.

create view Month_Feb as
select rownum AS day_of_the_month ,
p1.First_Date_Of_Month+rownum-1 AS date_of_the_day from period p1, period p2, period p3
where
p1.First_Date_Of_Month = '1-FEB-2000'
and rownum <= p1.Number_Of_Days;

select * from Month_Feb

     2>
DAY_OF_THE DATE_OF_THE_DAY
