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 always thought of "Friday week" as "Friday plus a week" rather than "next week's Friday".

[antod]

yeah, that's a better way of expressing it.

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.

Never seen or heard this in New Zealand from native speakers.

We must move in different circles then ;)

Maybe I should ask my kids...

My kiwi teenage daughter and her friend didn't really use it, but did hear it used occasionally.

Interestingly they both had different definitions of Next Friday though, and both thought there was only one way of defining it.

I’m Australian and I’ve heard this a lot

Likewise. I'm Australian and have used it regularly for a long time. My parents have always used it.
