Hello, Thanks for your reply. I made the assignments in my init.el file, as follows:
(load "utilvilf") ; frame parameters, font (load "cal-dst") ; I noticed that cal-dst was not initially loaded (setq calendar-daylight-savings-starts '(bv-calendar-dst-starts year)) (setq calendar-daylight-savings-ends '(bv-calendar-dst-ends year)) (setq calendar-daylight-time-offset 60) (setq calendar-daylight-savings-starts-time 180) (setq calendar-daylight-savings-ends-time 180) The two functions, bv-calendar-dst-starts and bv-calendar-dst-ends are defined in utilvilf (see above) as follows: (defun bv-calendar-dst-starts (year) "Daylight Savings Start" (calendar-nth-named-day -1 0 3 year) ) (defun bv-calendar-dst-ends (year) "Daylight Savings End" (calendar-nth-named-day -1 0 10 year) ) when I tested the two functions, they give the correct answer for the year 2013: (3 31 2013) and (10 27 2013) Regards, Bostjan
