SUMMARY
This step-by-step article describes how to use the NETWORKDAYS function with multiple holidays in Microsoft Excel 2000.
When you use the NETWORKDAYS function with multiple holidays, you can enter the holidays as cell references or in the serial number
format, and you must enclose the dates in braces ({}).
In the NETWORKDAYS function, dates in the form of text are ignored
if your worksheet is in the 1904 date system. Dates represented as serial numbers are accepted.

NETWORKDAYS
The NETWORKDAYS function returns the number of whole working days
between two dates. You can use the holidays parameter to exclude specific
dates from the calculation. You can enter starting and ending dates
directly as serial numbers, as text, through a cell reference, or by
using the DATEVALUE function. You can also enter single holidays
this way. However, you must enter multiple holidays in the serial
number format only, and you must enclose the set of holiday dates in
braces ({}).
NOTE: If the NETWORKDAYS function returns a #NAME error, follow these steps:
- On the Tools menu, click Add-Ins.
- Click to select the Analysis ToolPak check box. Click OK.
- Click Yes if you receive an installation or update message.
- After the installation or update, click outside the cell that contains the formula, click to select the cell again, and then press ENTER.

DATEVALUE
The correct way to indicate dates in the form of text is to use the
DATEVALUE function. Also, if you are using an array constant to
specify multiple "text" dates for the holidays argument, you must
enclose the array constant within the DATEVALUE function. An example
is provided in the Microsoft Excel Help file.

Examples That List Dates in the Function
=NETWORKDAYS(DATEVALUE("1/1/92"),DATEVALUE("12/31/92"), DATEVALUE({"12/24/92","12/25/92"}))
-or-
=NETWORKDAYS(DATEVALUE("1/1/92"),DATEVALUE("12/31/92"),{"12/24/92","12/25/92"})
-or-
=NETWORKDAYS(DATEVALUE("1/1/92"),DATEVALUE("12/31/92"),{33962,33963})

Examples That Use Cell References
A1: 12/24/92
A2: 12/25/92
Then, type the following formula in cell D1:
=NETWORKDAYS(DATEVALUE("1/1/92"),DATEVALUE("12/31/92"),A1:A2)
-or-
A1: 1/1/92
A2: 12/31/92
A3: 12/24/92
A4: 12/25/92
Then, type the following formula in cell D1:
=NETWORKDAYS(A1,A2,A3:A4)
Both of the examples above give 260 as the result.
You cannot, however use the following:
A1: 12/24/92
C1: 12/25/92
Then, type the following formula in cell D1:
=NETWORKDAYS(DATEVALUE("1/1/92"),DATEVALUE("12/31/92"),{A1,C1})
You receive a reference error because the cell references do not translate into date serial numbers.
