how to calculate next sunday and format to string?

[Sebastian Meisel]

Hallo,

I'd like to have the function that return the date of next sunday, or  
any other weekday as a formated string.

(formate-time-string-for-next-weekday "7" "%u.%m.%Y")
    -> "13.5.2007"

Thanks for any hints.

(require 'calendar)
(setq calendar-date-display-form '((format "%2s.%2s.%4s" (substring
(concat "0" day) -2) (substring (concat "0" month) -2) year)))

(calendar-date-string (calendar-nth-named-day in-n-wochen week-day-number
       (string-to-number month) (string-to-number year) (string
-to-number day))))

did the trick, where in-n-wochen means and week-day-number are
selfexplaining variables.
