Hi T.Valko,
I appreciate your formula. It works fine.
But I need a favour from you can you please breakup this formula because I am unable to understand the logic behind this.

In Excel dates are really just numbers formatted to look like dates. These numbers are the count of days that have passed since a base date. The default base date is January 1 1900. These counts are known as the date serial number.
January 1 1900 = date serial number 1
Each successive day the date serial number increases by 1:
January 1 1900 = date serial number 1
January 2 1900 = date serial number 2
January 3 1900 = date serial number 3
January 4 1900 = date serial number 4
January 5 1900 = date serial number 5
January 1 1975 = date serial number 27395
September 1 2011 = date serial number 40787
In the formula:
=SUMPRODUCT(--(WEEKDAY(ROW(INDIRECT(A2&":"&B2)),2)<7),--(ISNA(MATCH(ROW(INDIRECT(A2&":"&B2)),C2:C5,0))))
We use ROW(INDIRECT(A2&":"&B2)) to generate an array of the date serial numbers based on the dates in A2 and B2.
A2 = 9/1/2011
B2 = 9/7/2011
The array of date serial numbers are passed to the WEEKDAY function. Since we want to count weekdays from Monday to Saturday we test to see if they are less than weekday 7 which is Sunday.

WEEKDAY(ROW(INDIRECT(A2&":"&B2)),2)<7
That expression will return an array of TRUE or FALSE.
Weekday is less than 7 = TRUE otherwise = FALSE

Since SUMPRODUCT works with numbers we have to convert those logicals to numbers. One way to do that is by using the double unary minus --.
--(WEEKDAY(ROW(INDIRECT(A2&":"&B2)),2)<7)
--TRUE = 1
--FALSE = 0

That takes care of testing for the weekdays. Now we need to test for holiday dates to be excluded from the count.
We do that with this expression:
ISNA(MATCH(ROW(INDIRECT(A2&":"&B2)),C2:C5,0)))
We test to see whether any of the dates within our date range are listed as a holiday. If a date is not listed as a holiday then MATCH will return the #N/A error. If a date is listed as a holiday then MATCH returns a number that is the relative position of the matched date within the holiday list array.
This array of #N/A errors and numbers is passed to the ISNA function where we test for the #N/A error.
This will return an array of TRUE or FALSE
#N/A = TRUE
number = FALSE
Book1 |
---|
|
---|
| A | B | C |
---|
1 | Date | Serial # | ISNA(MATCH |
---|
2 | 9/1/2011 | 40787 | TRUE |
---|
3 | 9/2/2011 | 40788 | TRUE |
---|
4 | 9/3/2011 | 40789 | TRUE |
---|
5 | 9/4/2011 | 40790 | TRUE |
---|
6 | 9/5/2011 | 40791 | False |
---|
7 | 9/6/2011 | 40792 | TRUE |
---|
8 | 9/7/2011 | 40793 | TRUE |
---|
|
---|
Once again we have to convert the array of logicals to numbers:
Book1 |
---|
|
---|
| A | B | C | D |
---|
1 | Date | Serial # | ISNA(MATCH | -- |
---|
2 | 9/1/2011 | 40787 | TRUE | 1 |
---|
3 | 9/2/2011 | 40788 | TRUE | 1 |
---|
4 | 9/3/2011 | 40789 | TRUE | 1 |
---|
5 | 9/4/2011 | 40790 | TRUE | 1 |
---|
6 | 9/5/2011 | 40791 | False | 0 |
---|
7 | 9/6/2011 | 40792 | TRUE | 1 |
---|
8 | 9/7/2011 | 40793 | TRUE | 1 |
---|
|
---|
So, after executing our 2 tests we end up with 2 arrays of 1s and 0s:
Array1:
--(WEEKDAY(ROW(INDIRECT(A2&":"&B2)),2)<7)
Array2
--(ISNA(MATCH(ROW(INDIRECT(A2&":"&B2)),C2:C5,0)))
Book1 |
---|
|
---|
| A | B |
---|
1 | Array1 | Array2 |
---|
2 | 1 | 1 |
---|
3 | 1 | 1 |
---|
4 | 1 | 1 |
---|
5 | 1 | 0 |
---|
6 | 0 | 1 |
---|
7 | 1 | 1 |
---|
8 | 1 | 1 |
---|
|
---|
These arrays are then multiplied together:
Book1 |
---|
|
---|
| A | B | C | D |
---|
1 | Array1 | Array2 | Multiplied | Result |
---|
2 | 1 | 1 | 1 * 1 | 1 |
---|
3 | 1 | 1 | 1 * 1 | 1 |
---|
4 | 1 | 1 | 1 * 1 | 1 |
---|
5 | 1 | 0 | 1 * 0 | 0 |
---|
6 | 0 | 1 | 0 * 1 | 0 |
---|
7 | 1 | 1 | 1 * 1 | 1 |
---|
8 | 1 | 1 | 1 * 1 | 1 |
---|
|
---|
The results of the multiplication are then summed by the SUMPRODUCT function:
=SUMPRODUCT({1;1;1;0;0;1;1})
=5
So, the count of "networkdays", Monday thru Saturday excluding holidays is:
=SUMPRODUCT(--(WEEKDAY(ROW(INDIRECT(A2&":"&B2)),2)<7),--(ISNA(MATCH(ROW(INDIRECT(A2&":"&B2)),C2:C5,0))))
=5
