How can I get BibTeX to show months in another language than English?

Question

I'm using three-letter abbreviations in BibTex for the months, but when I compile my document, the month-names come out in English.

Can I somehow change the output language?

I'm using natbib, but don't mind switching back to vanilla BibTeX if that's required.

Answer 1

I believe the output language of the three-letter month abbreviations is controlled by the bibliography style. See, for example, these French bibliography styles.
