On Sunday (Monday, Tuesday etc.) in reported speech

[Nonverbis]

"When you come to see me on Sundsy, I will show you my new dress", she said to me.

What troubles me is on Suday.

Analogy with 'next'. Next Sunday is only related to the present moment.
In reported speech is the next Sunday. Or the following Sunday?

Is "on Sunday" is related to the present moment?
Is it "the following Sunday" in reported speech?

She told me that when I came to see her on the following Sunday, she would show me her new dress.

That's all basically right, yes.

They are Germans. But anyway, they seem to be teachers.

Is it a mistake?

No. It's one possible way of reporting the direct speech. There are alternatives for all ten questions, depending on the time of the reporting.

So, if it happened long ago, then should we switch to "Alice complained that she had spent all her pocket money the Monday before"?

 

[5jj]

There are three times involved:

1. The Monday when Alice spent all her pocket money,
2. The day on which Alice complained about this,
3. The day on which Alice's words were reported.

The words used of the Monday depend on the relationship between those words. For example, if Alice complained on the Thursday three days after the spending, and her words were reported two days after that, 'on Monday' would be fine, and 'the Monday before' would be incorrect.

Note my corrections above. Take care with your spelling. You spelled "Sunday" wrong twice in two consecutive sentences.
