Calculating a future date

C

How can we calculate a future date? For instance we need to calculate 45 days
from a date for a follow up in billing. So we need to determine the new date.
We can't figure out how to do this? Can you help? Thanks

Add 45 days

assume the date is in A1


=A1+45


if you want business days


=WORKDAY,A1,45,Holiday)

where Holiday is a range of cells with public holidays

Note that the latter is part of the Analysis ToolPak and needs to be
installed if it is not installed when Excel is installed (it is not
installed using default settings)

However it comes with Excel but you need the Office/Excel CD

Just a typo:
=WORKDAY,A1,45,Holiday)
should be:
=WORKDAY(A1,45,Holiday)

And in xl2007, it's built into excel--not part of the analysis toolpak <vbg>.

It is still part of the ATP in 2007, the only difference is that it get's
installed. You can still remove it I believe?

I don't think so.

The worksheet functions have been incorporated into excel proper. The data
analysis tools are still part of the analysis toolpak.

At least that was the way I read this:

Unlike Solver, we have done some major work with the ATP this release to move
the formulas that have been part of it in previous versions of Excel into the
core Excel calculation engine, but the functionality available through the Data
tab has remained the same (again, with updates for increased limits).


And in my simple tests, =workday() will still work if the Analysis tookpak isn't
loaded.
