Refining a query to only show entries for the current week

Question

Hello.
Does anyone know how to modify a query to only show records that have dates in the current week? Records have a start date and a finish date so the query should recognise that an entry may be valid for more than one week?
Kind Regards,

Assuming week ends on a saturday and dates aren't NULL - change as appropriate - this is one way
All rows....
SELECT TO_CHAR (begin_date, 'DD-Mon-YYYY HH24:MI:SS') AS begin_date
, TO_CHAR (end_date, 'DD-Mon-YYYY HH24:MI:SS') AS end_date
FROM mydates
ORDER BY begin_date;
BEGIN_DATE,END_DATE
05-Jul-2011 06:49:25,15-Jul-2011 06:49:25
05-Jun-2011 06:48:57,15-Jun-2011 06:48:57
15-Jun-2011 06:48:29,25-Jun-2011 06:48:29
25-Jun-2011 06:47:57,05-Jul-2011 06:47:57
Current week rows....
SELECT TO_CHAR (begin_date, 'DD-Mon-YYYY HH24:MI:SS') AS begin_date,
TO_CHAR (end_date, 'DD-Mon-YYYY HH24:MI:SS') AS end_date
FROM mydates
WHERE TRUNC (begin_date) < NEXT_DAY (TRUNC (SYSDATE) - 1, 'Sat') + 1
AND TRUNC (end_date) > NEXT_DAY (TRUNC (SYSDATE) - 1, 'Sat') - 7
ORDER BY begin_date
BEGIN_DATE,END_DATE
15-Jun-2011 06:48:29,25-Jun-2011 06:48:29
