This works for me with the regional date setting as U.S. English.

=WEEKDAY(--($A$9&"/"&MONTH($A10&1)&"/"&B$9),2)5

Hi,
I have a table with the months (January - December) on the right (Column
A)
and the numerical days of the month (1-31) across the top (Row 9). Cell
A9
contains the year (2009)

I want to condition the format of each cell that represents a weekend day
to
be yellow fill.

I have the conditional formula(s) that performs this on cell B10 as:

=WEEKDAY((DATEVALUE(CONCATENATE(A10,"/",B9,"/",A9))),1)=1
=WEEKDAY((DATEVALUE(CONCATENATE(A10,"/",B9,"/",A9))),1)=7
=WEEKDAY((DATEVALUE(CONCATENATE(A10,"/",B9,"/",A9))),1)<71

I am trying to replace the A in cell reference A10 with a reference of
"ROW()" to give me the month of same row as the reference cell, and then
also
replace the B in cell reference B9 with a reference of "COLUMN()" to bring
in
the correct data.

can anybody help, or recommend another way to arrive at the solution?

Thanks in advance
