Don't limit yourself to 52 weeks, Booth. Fiscal weeks could be 52, 53, or
even 54 (once every 28 years - 2000 was one of them). I remember having to
tweak things to deal with that 54 week year.

Subject: Re: Get Start Date of a Week Number

I love these kinds of problems. :) Questions for you: You speak of
already grouping the sales by week.
What method are you using for that, because that would probably point to a
similar way to get the date for the week.
Are you are needing 52 columns for each report?
Is column 1 always the first week of the year?

Thank you for the feedback. In the forecast I am getting arbitrary
dates and quantities. The person getting the report simply wanted the
quantities accumulated by week. So, if I got data for Monday and
Tuesday of the same week, I would add those together.

In my report, I had a row for each item and then a column for each week.
It might look like this:

Item, Week 1, Week 2

And so on.

After generating that output, the user then asked to have the start
date for the week show instead of the week number so now it night look

Item, 2014-12-29, 2015-01-05

The 12/29 and 01/15 dates were just from a calendar I was looking at.
I do not think it matters at all if the definition of the week is the
ISO one or not. The main thing is that I am consistent and put dates
as the column headings and not week numbers anymore.

I think Birgitta's solution will work, but I am not in a place to try
it out at the moment.

If you've got other thoughts though, just let me know.

Thanks to all who replied so far!
