THE ERROR WAS WITH A DOLLAR SIGN
THANKS IT WORKS GREAT!!
For marking the weekends use the WEEKDAY function
=WEEKDAY(E$1,2)5
For marking the days from your startdate unto and including the
enddate add a second rule and use
=AND(E$1=$C2,E$1<=$D2)
Use the brush to copy these conditiond from column E to the right.

This will be easy for a VB coder: I have a row with calender dates across
about 100 days (cells E:DV). I want the colums representing weekends to be
autofilled and remain unaffected by subsequent conditional formatting (or vb
code). Then (this is the subsequent part) rows below must be filled between
date ranges obtained from cells from columns, say C and D. Columns C being a
start date and D an end date. Note I have used the WORKDAY FUNCTION to
identify weekends through numbers 1 - 7, if that would help)

Hi Kobus,

Assuming you have the startdate in cell C2 and the enddate in cell D2

You can solve this with conditional formatting only.
