DateDiff("w") -- problem

[zSplash]

I am trying to count weekdays, using the "w" argument unsuccessfully. I get
the same value for "w" (weekday) as I do for "ww" (week). What am I doing
wrong?
Code:
estDays=DateDiff("w", ufm1.Calendar1, ufm1.Calendar2)

TIA

I'm not aware of the "w" or "ww" arguments. Where did you find them
documented?

 

[zSplash]

Found in the Help documentation for Excel ("DateDiff Function").

Hi Niek!

zSplash is talking about the vba DATEDIFF not the mysterious Workbook
function DATEDIF

Datediff is documented in Help for all versions since at least Excel
97.

For the mysterious Worksheet function look here

Hi zSplash!

I think that you are misunderstanding what DATEDIFF means by "w" and
"ww" arguments.

Extract from Help:

When interval is Weekday ("w"), DateDiff returns the number of weeks
between the two dates. If date1 falls on a Monday, DateDiff counts the
number of Mondays until date2. It counts date2 but not date1. If
interval is Week ("ww"), however, the DateDiff function returns the
number of calendar weeks between the two dates.

Both are counting weeks which is why in your case you are getting the
same answer.

To count weekdays use the Analysis ToolPak NETWORKDAYS function.

Absolutely right, Norman. I always assumed they were just the VBA and the SS
version of one and the same thing, but that turns out to be completely
wrong.

Thanks!

Thanks, Norman, for the help. I guess I just didn't read the expanded help,
and assumed. Sorry.

So, how do I access (or install, if necessary) the "Analysis Toolpack"
functions? This is new to me. (I don't see it in my References...)

Hi zSplash!

You and me both! I was misled by the intro description and didn't look
closer until I got the same results that you did.

Last resort? Read The Fine Manual.

See you around the newsgroups.

is it available under tools=>Addins? If so, check both Analysis Tookpak
and Analysis Toolpak - VBA. The later contains the VBA callable versions of
the functions.

If not go to the control panel and do add/remove software and start office
install.
