Huge calendar prompt. OK fine. Could be also used to show upcoming appointments. Emacs must have those date/time features and adding times somewhere. But where? (info "(elisp) Time Calculations") time-add is a built-in function in ‘src/timefns.c’. (time-add A B) In the manual there is more references: (let ((time (decode-time nil nil t)) (delta (make-decoded-time :month 2))) (encode-time (decoded-time-add time delta))) (make-decoded-time :hour 10 :minute 20) => (nil 20 10 nil nil nil nil nil nil) This adds 360 seconds to current-time: (time-add (current-time) 360) (defun my-days (days) "Returns seconds for days" (* 24 3600 days)) (defun my-minutes (minutes) "Returns seconds for minutes" (* 60 minutes)) (my-minutes 35) 2100 (format-time-string "%H:%M" (current-time)) "10:57" (time-add (current-time) (my-minutes 35)) (24537 50767 754967 229000) (format-time-string "%H:%M" (time-add (current-time) (my-minutes 35))) "11:33" So adding works in plain Emacs. What I do not know is how to convert 10:57 time to TIME format like: (24537 50767 754967 229000) And because function requires only time as hours and minutes, the date would not matter. Once that is found, how to convert any TIME:MINUTES to that TIME format: (24537 50767 754967 229000) then it will be easy to make function that adds minutes or specified hours or minutes to it and produces a sequence.
