Date substraction - A1 has 4/2/2008 and I want to subtract three days.
Therefore, the answer is 3/30/2008 (Sunday) then I want to fall back to
Friday 3/28/2008.

I don't believe that is what th OP asked.

Yours gives for Tuesday 4/1/2008 -- Thursday 3/27/2008

But 4/1/2008 less three days is Saturday 3/29/2008, so, by his request, you
should only fall bact to Friday, not Thursday.

=WORKDAY(A1-2,-1)

The OP doesn't seem to have reached some servers, but it appears from the
quoted material that the subject line talked of subtracting 2 days whereas
the text talked of subtracting 3 days, so I'm not surprised that TM and Ron
were both confused. :-)

The next confusion occurs as to whether the OP wanted to count back in
working days (as TM's & Ron's formulae both do), or count back in days &
then (if a weekend) find the previous working day (as the subject line
implied).

Once the question is clear, hopefully somone can come up with a suitable
answer.

My response was based on the quote showing the OP's example, where he
subtracted three ordinary days and then one (or two) more if the result was a
Saturday or Sunday. I never saw the original post, either.

But he should be initially counting back in days (and not workdays), because if
one counted back in Workdays, the result would never be a Saturday or Sunday.
