With RANGE_TEMP as (

SELECT
    STARTPERIOD start_date,
    ENDPERIOD end_date 
FROM
    TABLE_DATA -- YOUR TABLE WITH ALL DATA DATE

), DATE_TEMP AS (

SELECT
    (start_date + LEVEL) DATE_ALL
FROM
    RANGE_TEMP
CONNECT BY LEVEL <= (end_date - start_date)

), WORK_TMP as (

SELECT
    COUNT(DATE_ALL) WORK_DATE
FROM
    DATE_TEMP
WHERE
    TO_CHAR(DATE_ALL,'D', 'NLS_DATE_LANGUAGE=ENGLISH') NOT IN ('1','7')

), BUSINESS_TMP as (

SELECT
    COUNT(DATE_ALL) BUSINESS_DATE
FROM
    DATE_TEMP
WHERE
    TO_CHAR(DATE_ALL,'D', 'NLS_DATE_LANGUAGE=ENGLISH') IN ('1','7')

) SELECT L.WORK_DATE, H.BUSINESS_DATE FROM BUSINESS_TMP H, WORK_TMP L ;
