Terry, see the attached
Columns A and B are both conditionally formatted to show weekends in grey, but today's date will always show in red, taking precedence over the weekend formatting (I changed today's date in I1 to tomorrow to show what happens on a Saturday). Is that the sort of thing you wanted?
Note: I created this in Excel 2007 as that's all I have access to at the moment but I saved as an Excel 2003 file so it should work fine in that version......
