Answer 1

This is some sample program and still can be tuned for performance.
DECLARE
l_start_date DATE := To_Date('01-JAN-2007','DD-MON-YYYY');
l_end_date DATE := To_Date('31-JAN-2007','DD-MON-YYYY');
l_count NUMBER;
l_cur_date DATE;
l_exist NUMBER;
BEGIN
l_count := l_end_date - l_start_date;
FOR i IN 0..l_count
LOOP
l_cur_date := l_start_date + i;
l_exist := 0;
SELECT Count(1)
INTO l_exist
FROM table_name
WHERE date_column = l_cur_date
AND ROWNUM < 2;
-- Use trunc on dates if required.
IF l_exist = 0 THEN
Dbms_Output.put_line(l_cur_date);
END IF;
END LOOP;
END;
