I learned in Iran that referring to the future requires only three terms: tomorrow, after tomorrow, and in ten days.
For the first year there, I persisted in behaving those terms meant the same thing as their English equivalents.
Tomorrow to me meant the day after today. And after tomorrow meant a day or two later, an interpretation I considered pretty generous as being less precise than the day after tomorrow. Those were the usual answers.
