# Sarah El Deeb and Lee Keath of AP report that the Egyptian government says
# the change is because of blackouts in Cairo, even though Ahram Online (cited
# above) says DST had no affect on electricity consumption. There is
# no information about when DST will end this fall. See:

! # For now, guess that later spring and fall transitions will use
! # 2010's rules, and guess that Egypt will switch to standard time at
! # 24:00 the last Thursday before Ramadan, and back to DST at 00:00 the
! # first Friday after Ramadan. To implement this,
! # transition dates for 2015 through 2037 were determined by running
! # the following program under GNU Emacs 24.3, with the results integrated
! # by hand into the table below. Ramadan again intrudes on the guessed
! # DST starting in 2038, but that's beyond our somewhat-arbitrary cutoff.
! # (let ((islamic-year 1436))
! # (while (< islamic-year 1460)
! # (let ((a (calendar-islamic-to-absolute (list 9 1 islamic-year)))
! # (b (calendar-islamic-to-absolute (list 10 1 islamic-year)))
! # (friday 5))
! # (while (/= friday (mod a 7))
! # (setq a (1- a)))

+ # From Steffen Thorsen (2015-04-08):
+ # Egypt will start DST on midnight after Thursday, April 30, 2015.
+ # This is based on a law (no 35) from May 15, 2014 saying it starts the last
+ # Thursday of April.... Clocks will still be turned back for Ramadan, but
+ # dates not yet announced....

+
+ # From Ahmed Nazmy (2015-04-20):
+ # Egypt's ministers cabinet just announced ... that it will cancel DST at
+ # least for 2015.

! # http://english.ahram.org.eg/WriterArticles/NewsContentP/1/128195/Egypt/No-daylight-saving-this-summer-Egypts-prime-minist.aspx
! # "Egypt's cabinet agreed on Monday not to switch clocks for daylight saving
! # time this summer, and carry out studies on the possibility of canceling the
! # practice altogether in future years."
! #
! # From Paul Eggert (2015-04-20):
! # For now, assume DST will be canceled. Any resumption would likely
! # use different rules anyway.
