# From Paul Eggert (2015-04-08):
332
# For now, guess that later spring and fall transitions will use
333
# 2014's rules, and guess that Egypt will switch to standard time at
334
# 24:00 the last Thursday before Ramadan, and back to DST at 00:00 the
335
# first Friday after Ramadan. To implement this,
336
# transition dates for 2015 through 2037 were determined by running
337
# the following program under GNU Emacs 24.4, with the results integrated
338
# by hand into the table below. Ramadan again intrudes on the guessed
339
# DST starting in 2038, but that's beyond our somewhat-arbitrary cutoff.

# "Egypt's cabinet agreed on Monday not to switch clocks for daylight saving
338
# time this summer, and carry out studies on the possibility of canceling the
339
# practice altogether in future years."
341
# From Paul Eggert (2015-04-20):
342
# For now, assume DST will be canceled. Any resumption would likely
343
# use different rules anyway.
