Doubts regarding Time Series Measures

Question

Hi,
In my instance i have two calendars
1) Enterprise(or) Fiscal Calendar (Aug to July)
2) Gregorian Calendar (Jan to Dec).
So now my question is if we apply To Date function using Both Calendars how will it work.
For ex: If i create an Year To Date function using Gregorian Calendar then it will fetch results from Jan 1st to Till Date. And same if i used Enterprise Calendar then it will fetch results from Aug 1st to Till Date.
Is my above understanding correct. Correct me if am wrong any where.
And now i have one more requirement, My client wants to change the dates in the calendar i mean for Fiscal Calendar they dont want from (Aug to July) but From (Dec to Dec) is this possible, if so please clarify how and where..
Help is greatly appreciated.

Raj,
For your requirement I wrote a procedure in which for the date '01-jan-2010' it converts to the financial year of '26-Dec-2009' and the same is updated inside your calendar_table in the column fis_dat based on which you can easily find your fiscal_year, month and so on. The same can be much simplified and i ll update if find time.... Check and revert me back.
Create or replace procedure fin_cal
as
begin
DECLARE
temp_date date;
fisc_date date;
temp_fisc_date date;
previous_date date;
pre_year int;
year_date int;
cursor c1 is select trunc(date_time) from dates1 where time_key >= 20100101 and time_key <= 20120101 order by trunc(date_time); // calculated from 1st jan 2010 -2012
begin
open c1;
loop
fetch c1 into temp_date;
exit when c1%notfound;
year_date:=to_number(to_char(to_date(temp_date,'dd-mm-yy'),'yyyy'));
pre_year:=year_date-1;
if to_char(temp_date,'dd')='01' and to_char(temp_date,'mm')='01' then
fisc_date:=to_date(pre_year||'12-24','YYYY-MM-DD'); // the initial date is 24-12-prioryear...
dbms_output.put_line(fisc_date);
update dates1 set fis_dat=fisc_date where trunc(date_time)= trunc(temp_date);//fis_dat is the column in the table
else
select fis_dat into previous_date from dates1 where trunc(date_time)=trunc(temp_date)-1;
temp_fisc_date:=TO_DATE(TO_CHAR(previous_date,'YYYY-MM-DD'),'YYYY-MM-DD') + 1;
update dates1 set fis_dat=temp_fisc_date where trunc(date_time)= trunc(temp_date);
temp_fisc_date:='';
end if;
end loop;
end;
end;
begin
fin_cal();
end;
