Defining schedule in a scheduler sets the schedule to be started in next year instead of this year 2

I am trying to create a schedule that will comply to the following requirements.

1. Runs on JAN,MAY,JUL,SEP

2. On the 3rd saturday of the month

3. Runs at 3am

I created a schedule as follows

sys.dbms_scheduler.set_attribute( name => '"OWNER1"."SCHEDULE_JANMAYJULSEP_3RD_SAT"'

                                 , attribute => 'repeat_interval', 

                                   value =>'FREQ=YEARLY;BYMONTH=JAN,MAY,JUL,SEP;BYDAY=3SAT; BYHOUR=3'); 

The problem we notice was this was getting scheduled to start on Jan 19, 2013 as opposed to May 19, 2012.

Any thoughts or comments much appreciated. 

Thanx,

Sam
