+
+# From Roozbeh Pournader (2003-03-15):
+# This is an English translation of what I just found (originally in Persian).
+# The Gregorian dates in brackets are mine:
+#
+#	Official Newspaper No. 13548-1370/6/25 [1991-09-16]
+#	No. 16760/T233 H				1370/6/10 [1991-09-01]
+#
+#	The Rule About Change of the Official Time of the Country
+#
+#	The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
+#	based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
+#	of the Country's Organization for Official and Employment Affairs,
+#	and referring to the law for equating the working hours of workers
+#	and officers in the whole country dated 1359/4/23 [1980-07-14], and
+#	for synchronizing the official times of the country, agreed that:
+#
+#	The official time of the country will should move forward one hour
+#	at the 24[:00] hours of the first day of Farvardin and should return
+#	to its previous state at the 24[:00] hours of the 30th day of
+#	Shahrivar.
+#
+#	First Deputy to the President - Hassan Habibi
+#
+# From personal experience, that agrees with what has been followed
+# for at least the last 5 years.  Before that, for a few years, the
+# date used was the first Thursday night of Farvardin and the last
+# Thursday night of Shahrivar, but I can't give exact dates....
+# I have also changed the abbreviations to what is considered correct
+# here in Iran, IRST for regular time and IRDT for daylight saving time.
+
+# From Paul Eggert (2003-03-15)
+# Go with Shanks before September 1991, and with Pournader thereafter.
+# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates.
 # The Persian calendar is based on the sun, and dates after around 2050
 # are approximate; stop after 2037 when 32-bit time_t's overflow.
