The information you need can be found here: http://www.postgresql.org/idocs/index.php?functions-datetime.html look specifically at the extract and date_part functions. You could get what you need by concatting th date value and the time value (with a space in between) casting the result as a timestamp and running it through the date_part function using the 'dow' parameter. Here's an example: processdata=# select date_part('dow', ('20/06/2001' || ' ' || '08:00:00')::timestamp); date_part ----------- 3 The number return is an integer between 0-6 where 0 is Sunday.
