Hello! A question about relative clauses

[Eandir]

Hi everyone! I'm new here... I'm Spanish

I came for a question I had in mind about relative clauses. I was wondering if you can use an adverb instead of the relative pronoun. For example, can you say:

This is the city where I live.
Haec est civitas ubi vivo.

Or you have to say something like:

Haec est civitas in qua vivo.
(This is the city in which I live.)

In the same way, could you say "The day when he came." as "Dies (ubi?) venit.", or "Dies in qua venit."
How to say "when"?

Thank you in advanced.

Hi Eandir, welcome

I'm just a beginner, but I'll try to answer your questions. If I'm wrong, please guys correct me.

Haec est civitas ubi vivo.

I've seen ubi used in these situations before so I'd say it's fully OK.

I can't answer about the other one. Dies cum venit? I'd say so, but I may be wrong.

Ok! Thank you a lot!

The answer would seem to be a resounding yes!!!

"Dies in qua venit."

As Ptolemyauletes and loqu say. And regarding the above, "dies quâ venit" without the preposition is also sufficient, unless I'm mistaken, because the ablative in itself without a preposition can express time when, as "die Mercuri", "on Wednesday".

Ut dicunt ptolemyauletes et loqu. Et quoad rem suprà citatam, et sufficit "dies quâ venit", nisi fallor, eâ ratione casus ablativus in ipso sine praepositione tempus cum exprimere potest, sicut "die Mercuri".
