[Plugin: WordPress SEO by Yoast] Translation for %%currentmonth%%

Hey,
first of all I would like to THANK YOU for that great Plugin.

I’m using %%currentmonth%% and %%currentdate%% in the Description. Unfortunately the month and date is displayed in english language. Is there a way to translate it into german ?

Thank you in advancd for your help.

Stefan
