Is there an easy way to create a list of all non-working days (Sat & Sun,
major holidays) between now and the year 2020? I want to use this range as
the "holidays" argument in the NETWORKDAYS function.

I could create this list by hand, but if it can be done with programming,
all the better! Thanks for any ideas you can give me.

Steve,

The easiest solution I can think of is running through a loop
mathematically to identify the Saturdays and Sundays. Start somewhere
like last Saturday then cycle through one week at a time adding 7 days
to identify all the Saturdays and 8 days to identify all the Sundays.
Adding them to a collection as you go. There aren't that many
holidays that eliminate work these days so you could choose to
identify those manually. Once you get rid of the 1352 Sat/Sun dates
over the next 13 years you're job looks a lot more manageable. A loop
can help you tie up the static holidays like new years and Christmas.
The non-static dates like Thanksgiving can be done with a little math
and a few variables. If you load all of these dates into an Array
then you can utiltize them in that function.

Thanks for the suggestions, Allen. I'll give them a shot.

Since NETWORKDAYS already excludes Saturdays and Sundays, I don't understand
why you would want to include those dates in your function.

I think you really only need a list of the holiday dates. Perhaps you could
find such a list on the web.

If not, then some are easy:

New Years
Christmas
July 4.

Some are a little more complicated:

Labor Day
Thanksgiving

Some are probably best done by looking them up in a table:

Easter

Some require knowledge of the rules for the particular corporation:

If Christmas is on a Saturday, is Friday a working day?

A formula for New Years might be:

=DATE(ROWS($1:2008),1,1)

as you copy/drag down, it will give you Jan 1 for the years from 2008 to
however far down you drag it.

Labor Day is the first Monday in September, so:

=DATE(ROWS($1:2007),8,31)-WEEKDAY(DATE(ROWS($1:2007),8,31)+6)+8

and copy/drag down.

and so forth.

Ron,

Thanks for the ideas. I realized going in it probably would take some time
to compile all the dates, but the formulas you gave me will help.
