Conditional Formatting

[Guest]

In Cell A1 I have the which for example is 1-21-06.
In Cell B1 I have the Weekday that represents, for this lets say it is
number 7.
In Cell C1 through C34 I would like the cell shaded yellow if it is Saturday
on Cell A1. How do I do this without macros, because I have no idea how to
create a macro? I have tried in the past but with no luck at all.

Highlight cells C1-C34 and select Format->Conditional Formating. Select
Formula Is and in the formula box put this formula exactly

=WEEKDAY($A$1)=7

be sure to include both =. Hit the Format button and go to the patterns
tab. Change the format to a yellow background color. Hit OK. Hit OK.
