Answer
Hi Harold,

I assumed you want the entire row, not just the date cell, to be greyed out. The are two ways to accomplish this: via conditional formatting, and via macro.  I chose the macro approach because putting conditional formatting in all the cells would add quite a bit of overhead to your workbook, and possibly interfere with other conditional formatting you might have.  So here is a simple macro that will do it:

Sub GreyWeekends()
  'greys out all rows of the active worksheet that have weekend dates in column A
  Dim iRow       As Long
  For iRow = 1 To Range("A65536").End(xlUp).Row
     If IsDate(Cells(iRow, "A")) Then
        If Weekday(Cells(iRow, "A"), vbMonday) > 5 Then Rows(iRow).Interior.ColorIndex = 15
     End If
  Next iRow
End Sub

To install this in your workbook go to the Visual Basic Editor (keyboard Alt-TMV), insert a new macro module (Alt-IM) and paste this code into the code pane.  To run the macro go back to Excel and Alt-F8, select the macro and click Run.

Keep Excelling.
