Reasonably commonly used in Commonwealth countries.
Next Friday is sometimes too ambiguous, you can never be sure you share the same definition with the other person. Is it the same as This Friday (the very next occurring Friday), or Friday Week (ie next week's Friday).
I heard it used this way in Australia, and I’ve heard it now and then in British TV programs. Only have heard it among very old timers in isolated areas in the US a few times when I was very young previously.
