Dates
 

I developing a small project plan in excel - starting with project end date
and subtracting task durations to get to start date. Using
=DATE(YEAR(D30),MONTH(D30),DAY(D30)-C29) to get to the next earlier date.
Problem is I need to exclude weekend dates. D30=end date. C29=duration of
task. How do I do that?

Dates
 

=WORKDAY(DATE(YEAR(D30),MONTH(D30),DAY(D30)),-C29)

however if you have a date in D30 you don't need the DATE function

=D30-C29

or


=WORKDAY(D30,-C29)

I already tried both of these
=workday(E24,D23) results in #NAME? and
=workDAY(DATE(YEAR(D30),MONTH(D30),DAY(D30)-C29)) results in #NAME?
what am I doing wrong? thx

Toolsadd-ins, select ATP (Analysis Toolpak)
and keep the installation CD handy.

It comes with Excel but might not be installed at first time,
if it is a company PC ask IT to install it if it doesn't install
when you check under add-ins

What you are doing wrong is not using Excel help for the WORKDAY function.
