All I can say is that we're working with open source code.  It took a
little bit of time, but I just tracked down at least one place where the
dayname strings are defined.  On my system it's

(defvar calendar-day-name-array
  ["Sunday" "Monday" "Tuesday" "Wednesday" "Thursday" "Friday" "Saturday"]
  "Array of capitalized strings giving, in order, the day names.")

(and apparently other places) in calendar.el.

I.e., just go in and change the names of the days to what you want.


Tell us if that does it... I'd be interested.
