Working with weekdays

[Barry Campbell]

Hi,

I am trying to add and subtract weekdays.

Example
I must schedule the delivery of the printer two days prior to the scheduled
7/10/2006 training date.

High Level Formula: Training Date - 2 days lead time = delivery date

What commands should I use to calculate the delivery date?

Assuming you do not want to include weekends as delivery dates.

=WORKDAY(A1,-2)

Where your training date is in A1. You can also have this ignore holidays. List your holidays in a range say C1:C10. Your formula would then be,

=WORKDAY(A2,-2,C1:C10)

If you want holidays and weekends included then just use

=A2-2

Try something like this:

For a date in A1

The below formulas set the Delivery date at 2 workdays prior to the date in
A1:

B1: =WORKDAY(A14,-2)
Note: the WORKDAY function is part of the Analysis ToolPak (ATP) addin,
which must be installed (if not already) and activated.<tools><add-ins>

OR...avoiding the ATP.....
B1: =A1-2-(WEEKDAY(A1)<4)*MIN(WEEKDAY(A1),2)

or....this
B1: =A1-CHOOSE(WEEKDAY(A1),3,4,4,2,2,2,2)

Format B1 as a date

Is that something you can work with?

If it can arrive over a weekend, just use

=A1-2

where A1 is the scheduled date. Otherwise use

=WORKDAY(A1,-2)
