Emacs calendar: show more than 3 months?

Question

In Emacs, when you display the calendar with M-x calendar, you get a three-month display – last month, this month, and next month – in a new window that\'s just 8 l

Answer 1

There doesn't seem to be an easy way to do this. I was able to knock up the following code, which will show all twelve months, in a row, in a separate frame.

(require 'cl)
(require 'calendar)

(defun twelve-month-calendar ()
  (interactive)
  (let ((calendar-buffer (get-buffer-create "12-month calendar"))
        (month 12)
        (year 2012))
    (set-buffer calendar-buffer)
    (setq calendar-frame (make-frame))
    (make-variable-buffer-local 'font-lock-face)
    (set-face-attribute 'default calendar-frame :height 70)
    (set-frame-width calendar-frame 300)
    (erase-buffer)
    (dotimes (i 12)
      (calendar-generate-month month year 0)
      (calendar-increment-month month year -1))
    (calendar-mode)))

You might need to tweak it a bit, depending on your screen/font size.
