user enter a date entry....

Data>Validation>Allow>Custom
Formula: =WEEKDAY(A1,2)<6

is it possible to validate a week, say, whenever a user enter Tuesday and
Friday, the range do not allow it......

Don't know what you mean by that.

thanks T. Valko for your assistance..
the syntax :
=weekday(a1,2)<6 is to avoid two day running one after another Saturday or
Sunday...

my objective is...

example:

I set a range of cell with validation date format that only allow Monday /
Tuesday / Thursday / Friday / Sunday...

and if user enter any date format that falls in Wednesday or Saturday, the
cell entry does not permit it.

is it possible to do such validation ?

very much appreciated for the assistance render

Try this:

=AND(WEEKDAY(A1,2)<>3,WEEKDAY(A1,2)<>6)

This will allow Mon, Tue, Thur, Fri and Sun

It will not allow Wed or Sat

Hi

You can use WEEKDAY to determine what day of the week a date
represents - so to avoid Sat/Sun you could use the following check
(returns True if not Sat/Sun, False otherwise):

=WEEKDAY(A1,2)<6

Hope this helps!
