+# 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....

+# Egypt's ministers cabinet just announced ... that it will cancel DST at
+# least for 2015.
 #
-# 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.
