Do you use Roman numerals in your country?

So I saw this post where people started to argue that using Roman numerals is pretentious. Then some pointed out that this is customary all across Europe, then many pushed back that it is not.

So do you use them in your country?

In Hungary we use them for various occasions.

Marking centuries, chapters of a book, number city districts, we use them to serialise laws, royalty and popes have roman numerals before their names, and probably there are other uses that I forgot to mention.
