Timestamp problems...wrong weeks.

Hello,

I’m having a problem with timestamps in postgresql.

I run the following query to pull dates in this format:

WEEK/MONTH/YEAR

However the data says that April 28^th 2004 was in week 4 of April and that April 29^th 2004 was in week 5 of april.

This is incorrect.

This is causing my reports to print out incorrect data.

Do you know why this would happen? Am I doing something wrong?

--SQL CODE

SELECT

current_timestamp,

completion_date,

to_char(current_timestamp,'W/MM/YYYY'),

to_char(completion_date,'W/MM/YYYY')

FROM anna_onestop_database_t

WHERE to_char(current_timestamp,'MM/YYYY') = to_char(completion_date,'MM/YYYY')

AND upper(solution_provider) = 'N0050961' AND status LIKE 'Closed - Completed'

--RESULTSET

Timestamptz                          |completion_date    |to_char  |to_char
