Change Excel day name to other languages
Solution 1:
You would have to put in the LanguageID into the format string:

Here you go:
=TEXT(TODAY(),"[$-407]DDDD")
this should result in
Donnerstag, Freitag, etc ...
And because I am alway unsure about english formulars, here is my original for german users:
=TEXT(HEUTE());"[$-409]TTTT")
this results in the current day in english instead of german language
Solution 2:
I changed below day names to my language and it works
=CHOOSE(WEEKDAY(B4),"Sun","Mon","Tue","Wed","Thu","Fri","Sat")
