Same problem in French. "Ce vendredi" (this Friday) is unambiguous. For the other one we can use. - "vendredi de la semaine prochaine" (Friday of next week)

Same problem in French. "Ce vendredi" (this Friday) is unambiguous. For the other one we can use. - "vendredi de la semaine prochaine" (Friday of next week) - "vendredi prochain, pas celui la mais l'autre" (Next Friday, not this one, the other one) - "vendredi en huit" (Friday in eight). "In eight" here means "from day 8", today is day 1, so "in eight" is next week.
