-# For now, guess that later spring and fall transitions will use

-# 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 24.4, 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.
