Maybe a little macro???

Option Explicit
Sub testme()

Dim iCtr As Long
Dim myDate As Date

myDate = DateSerial(2005, 8, 1)

For iCtr = DateSerial(Year(myDate), Month(myDate), 1) _
To DateSerial(Year(myDate), Month(myDate) + 1, 0)
Worksheets.Add after:=Worksheets(Worksheets.Count)
On Error Resume Next
ActiveSheet.Name = Format(iCtr, "dddd mm_dd_yyyy")
If Err.Number <> 0 Then
MsgBox "Error with date: " & Format(iCtr, "mm/dd/yyyy")
Err.Clear
Application.DisplayAlerts = False
ActiveSheet.Delete
Application.DisplayAlerts = True
End If
On Error GoTo 0
Next iCtr

End Sub

If you're new to macros, you may want to read David McRitchie's intro at:

(ps. I used August of 2005 for the month to add.)
