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

> # (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-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.
