hi
=if(A1="","",Text(A1,DDD))
you can use this technique whenever you are getting data that you don't want
but know that your formula is right such as the #DEV/0! error and others.

Col A contains a date that I enter.
Col B contains the formula =TEXT(WEEKDAY(A1), "DDD") which, when I enter a
date in Col A, returns the day of the week.

The entire Col B is formatted with the weekday formula. If Col A contains no
date, then Col B returns the weekday "Sat" all the way down the sheet. (Why
"Sat" I don't know.)

My question is: How can I hide the display in Col B until I populate Col A
with a date?
