Oracle to Retrieve Date records in week Give more suggestion

Question

Hai
I will be passing Date values in Weeks like "from date" and "to date" data's will be '01/2009'( From date) and '06/2009' (To_date).
01---> first week
06--> 6th week
Based on this first input value(01/2009) my records are displayed.
My query now will have the condition in "Where" clause as
Date_invoice <='03-jan-09'
this 03-jan-09 comes from first value ie 01/2009 LAST DATE OF THE FIRST WEEK OF 2009.
how to retrieve this?
Give me your suggestions
