Daily Note core plugin Dutch day in Title wanted

What I’m trying to do

I would like a Daily Note created at startup where the note title (that will become the filename) like this: 2025-07-06 Zondag
Where Zondag is Sunday in Dutch and with a capital letter.

Things I have tried

I was trying with Templater and also with Daily Note itself and puting YYYY-MM-DD dddd in the date format gives a dayname with a lowercase letter…

Can somebody please help me achieving this daily note with a dutch dayname and a capital letter?

Thanx

I switched my Obsidian interface to Dansk, set the Daily note format, and get the same:

The formats, in this case, are from momentjs. Hopefully someone can chime in here, but maybe try a web or chatbot search as to why the days are lowercase in Dutch? Is this just happening in Obsidian or other apps/services that use momentjs? Searches like that.

Aren’t day names in Dutch normally lower case? The template could use regular expressions to modify the name, if that’s what’s wanted.
