SUMMARY
When you use the Networkdays function to use a range of dates for the Holidays argument, you must either enter the dates in a range of cells or enclose the dates with array {} brackets.

This article includes a Visual Basic for Applications function that allows you to enter a beginning date and an ending date for a consecutive range of dates. The function will return the entire array of dates between the beginning and ending dates and can be used with the Holidays argument of the Networkdays function.

For additional information about the Networkdays function, please see the following article in the Microsoft Knowledge Base:

The following function returns an array of datevalues from the beginning date (BegDate) through the ending date (EndDate): Function DateSpan(BegDate As Date, EndDate As Date) As Variant Dim DateArray As Variant, i As Integer, Span As Integer BegDate = DateValue(BegDate) EndDate = DateValue(EndDate) Span = EndDate - BegDate + 1 ReDim DateArray(1 To Span) For i = 1 To Span DateArray(i) = BegDate + i - 1 Next DateSpan = DateArray End Function

Example Using the Function with Networkdays
This example will return the number of workdays (weekdays) between December 1, 1998 and January 1, 1999 with the dates between December 24 and January 1 indicated as holidays.

NOTE: Before using the Networkdays function, you must install the Analysis Toolpak add-in.

 In a new workbook, type the custom function DateSpan (illustrated above) into a new module sheet.
