Range Partitioning for the day of the week

Question

I have a logging table which i want to partition into 7 partition, each one for the day of the week, eg MON,TUE, WED. I am aware and I can do a list partition by creating a parition key which stores 'DY' of the week and this means that I need to add another column to the existing table.
I wanted to explore the option of creating a range parition based on the timestamp column that already exists. Can anyone let me know if this option is possible?
Example
create table test_partition
( log_id number,
log_date TIMESTAMP(6),
log_value varchar2(100)
PARTITION BY RANGE (log_date)
PARTITION p1_mon VALUES LESS THAN (), ---- Not sure what can be used here to create this parition.
PARTITION p2_tue VALUES LESS THAN (),
PARTITION p3_wed VALUES LESS THAN (),
PARTITION p4_thu VALUES LESS THAN (),
PARTITION p5_fri VALUES LESS THAN (),
PARTITION p6_sat VALUES LESS THAN (),
PARTITION p7_sun VALUES LESS THAN ()
Any oracle guru with some suggestion for this would be highly appreciated..
Cheers,
VJ

VJ,
Here is an example of daily partitioning , let me know if this is what you want or you can modify this even to weekly, monthly, quarterly and yearly partitions.
CREATE TABLE YY_EVENT
  PART_KEY       DATE                           NOT NULL,
  SUBPART_VALUE  NUMBER                             NULL,
  EVENT_NAME     VARCHAR2(30 BYTE)                  NULL,
  EVENT_VALUE    NUMBER                             NULL
TABLESPACE TEST_DATA
PARTITION BY RANGE (PART_KEY)
  PARTITION Y_EVENT_20090310 VALUES LESS THAN (TO_DATE(' 2009-03-11 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
    LOGGING
    NOCOMPRESS
    TABLESPACE TEST_DATA, 
  PARTITION Y_EVENT_20090311 VALUES LESS THAN (TO_DATE(' 2009-03-12 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
    LOGGING
    NOCOMPRESS
    TABLESPACE TEST_DATA
