change date parse to specific language

Hey,

I need help changing this:

Code:

---

$this->parseDate("j. F Y\, l",strtotime($this->date))

---

not to output in English but in another specific language. Is there any built-in function or do I have to code my own function?

Thanks for help.

Edit:
found language translations in
system/modules/backend/languages/*

*- for specific language

:)

Ok, found out that there is no translations for my language for parsedate.... Where can I find the files to translate dates and days, and months...??

What translations do you need? Contao 3 already comes with a lot of languages.

xchs:
I was looking for slovenian translations.

The problem was, that the words are capitalized, and should not be... But now i've found the files where I can change it my own translations.

Thanks for help.
