Testing a cell value for a specific weekday.
 

I either want to set up a data validation formula, or do something
similar to IF(ISBLANK()) kind of thing.

I want a cell called "week starting date" to be locked to only
Saturdays (or a numeric test where I can choose which day gets tested).

So the user would choose the 'week starting day' (or number) in one
cell, and then the formula would take that choice and validate entries in
another named cell.

Or simply raise a flag (message) if it isn't starting on a Saturday.

This makes my timesheet calendar begin with the right day first and
date the subsequent days correctly.

Hi
Assuming A1 = week starting date cell and the date is in B1. The formula in A1: =IF(WEEKDAY(B1)=7,"Saturday","").

or something along those lines!

Cool. Thanks. I'll work with that for a while.

you can also choose Data = Data Validation = Custom and enter the
formula (for cell A1):
=WEEKDAY(A1)=7 for cell A1

the cell can be custom formatted
[<8]General;dd/mm/yyyy
So you can enter 7 or any date for Saturday
