Hello,

I've run across a test error on the current HEAD.
When I run "make test" on my system, then test-org-archive/datetree
fails.

The test fails because the expected output should contain "Sunday",
but with a German locale the generated text is "Sonntag" instead
(which is the German translation of "Sunday").

The attached patch fixed the test for me.

Best regards
Christian
