Yes I did. I'll copy paste the answer. 

(defun insert-new-entry ()
   (interactive)
   (save-excursion
      (goto-char (point-max))
      (print "Asti")
      (define-key calendar-mode-map (kbd "RET") 'get-date)
      (calendar)
          (let* ((x (calendar-cursor-to-date))
                (time (encode-time 0 0 0 (nth 1 x) (nth 0 x) (nth 2 x))))
            (select-window (get-buffer-window "asti" t))
            (insert (format-time-string "%Y-%m-%d" time)))))

I didn't yet use the `calendar-mode-map`. Too tired. But I'm confident
that it'll work. 
So now I have all the pieces ;))))

Thanks you so much Emanuel, Yuri and Drew!!

P.S. I got this from org-read-date ;)
