Display Previous Weekday

[Cayle]

I have a field that shows the due date for a document to the client. The
document is being sent overnight, so the file needs to be prepared the day
before it is due to the client.

We currently use a visual board to show the upcoming due dates, but it would
be better if I were able to show the date we had to finish the document by,
instead of the due date. Is there a way to calculate the previous weekday
date?

ie. if the document is due Monday, April 16th, we would need to send it out
on Friday, April 13th.

Just a note, this is using InfoPath 2003 and SharePoint 2003

date calculations in IP2003, while not impossible, require significant
custom coding
