So if I have the following in my Org file

,-------------------------------------------
| +LANGUAGE: de
| +LATEX_HEADER: \usepackage[ngerman]{babel}
`-------------------------------------------

I get this in my LaTeX file:

,-------------------------------------
| \usepackage[ngerman, germanb]{babel}
`-------------------------------------

and I get \today is rendered correctly for German:

,-------------
| 26. Mai 2014
`-------------

However, without a \usepackage{babel} header and just

,--------------
| +LANGUAGE: de
`--------------

there is no \usepackage line in the LaTeX file for babel and I get

,-------------
| May 26, 2014
`-------------

The specific idiosyncrasy with German seems to be that there are 3
options with babel: german, ngerman, and germanb.  If the LATEX_HEADER
includes babel, then setting LANGUAGE will append germanb to the list of
language options given, if not already given.

So my problem is solved (thanks, Nick), although one question remains:

Does setting LANGUAGE, without \usepackage{babel} on its own actually
achieve anything for LaTeX, or is it just for other backends?

Cheers,

Loris
