Settings-About-Language in English but Date in German?

What I’m tryings to do

I want to display automatically (with templater) my Date written in German language (i.e. Montag, 11. Februar 2022) instead of english (Monday, 11. February 2022). But the System setting should stay in English. I assume that the challenge and that the reason I need your help/support. Appreciate every feedback/idea/tip. Many thanks in advance

Does this work for you, adding the code to a date template?

<%* moment.locale("de") -%>
<%"dddd, DD. MMMM YYYY") %>
