# 3:00 am Friday, July 20, 2012 and will again be advanced by 60 minutes

# August 20, 2012 from 2:00 am.

# From Paul Eggert (2013-03-06):

# Morocco's daylight-saving transitions due to Ramadan seem to be

# announced a bit in advance. On 2012-07-11 the Moroccan government

# announced that year's Ramadan daylight-saving transitions would be

# 2012-07-20 and 2012-08-20; see

# <http://www.mmsp.gov.ma/fr/actualites.aspx?id=288>.

#

# To estimate what the Moroccan government will do in future years,

# transition dates for 2013 through 2021 were determined by running

# the following program under GNU Emacs 24.3:

#

# (let ((islamic-year 1434))

# (while (< islamic-year 1444)

# (let ((a

# (calendar-gregorian-from-absolute

# (calendar-islamic-to-absolute (list 9 1 islamic-year))))

# (b

# (calendar-gregorian-from-absolute

# (calendar-islamic-to-absolute (list 10 1 islamic-year)))))

#(insert

# (format

# (concat "Rule\tMorocco\t%d\tonly\t-\t%s\t %2d\t 3:00\t0\t-\n"

# "Rule\tMorocco\t%d\tonly\t-\t%s\t %2d\t 2:00\t1:00\tS\n")

# (car (cdr (cdr a))) (calendar-month-name (car a) t) (car (cdr a))

# (car (cdr (cdr b))) (calendar-month-name (car b) t) (car (cdr b)))))

# (setq islamic-year (+ 1 islamic-year))))

#

# with the results hand-edited for 2020-2022, when the normal spring-forward

# date falls during the estimated Ramadan.

#

# From 2023 through 2038 Ramadan is not predicted to overlap with

# daylight saving time. Starting in 2039 there will be overlap again,

# but 32-bit time_t values roll around in 2038 so for now do not worry

# about dates after 2038.
