"October thirty-first"

Translation: la tridek-unua de oktobro

[JoshLingo1800]

When I first read this, I thought it said October thirty-fifth lol

I wonder (publicly), do folks whose native languages are "Romance languages" tend to use "la tridek-unu de oktobro" for this kind of sentence more than folks whose native languages are "Germanic Languages"?

Do folks whose native languages are "Germanic Languages" tend to use an of-&-the-free construct for this kind of sentence more than folks whose native languages are "Romance Languages"?

Are both constructs equally valid in Esperanto? Is one preferred over the other?

I'm just curious.
