Answer 1

Convert to hirjih date using:
select
to_char(sysdate,'YYYY/MM/DD','NLS_CALENDAR=''English Hijrah''') hijrih_date
from dual;
You can replace sysdate with the date of your choice.
Also I wrote this for my last project:
/* get hirjih date */
FUNCTION get_hijrah_date(
p_date in date,
p_date_format in varchar2
) return varchar2
is
v_hijrah_date varchar2(500);
begin
select
to_char(p_date,p_date_format,'NLS_CALENDAR=''English Hijrah''')
into v_hijrah_date
from dual;
return v_hijrah_date;
end get_hijrah_date;
So you can have get_hijrah_date(sysdate,'DD-MON-YYYY') from dual;
(or any other date formate of your choice)
