Microsoft Excel 97 for Windows

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.

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
