Hola excel programmers, I'm creating a scheduling system for fun and I need a simple if statement to detect if the day is a saturday. If it isnt, msgbox "sorry, starting date must be a saturday."

thinking of it this way, it would/should look something like this.

if worksheets("sheet1").range("a1").value <> saturday then
msgbox "sorry, starting date must be a saturday."
end if

Should hopefully be fairly simple


Thanks in advance.
Chris
