+# tzdb data for Africa and environs
+
+# This file is in the public domain, so clarified as of
+# 2009-05-17 by Arthur David Olson.
+
+# This file is by no means authoritative; if you think you know better,
+# go ahead and edit the file (and please send any changes to
+# tz@iana.org for general use in the future).  For more, please see
+# the file CONTRIBUTING in the tz distribution.
+
+# From Paul Eggert (2018-05-27):
+#
+# Unless otherwise specified, the source for data through 1990 is:
+# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
+# San Diego: ACS Publications, Inc. (2003).
+# Unfortunately this book contains many errors and cites no sources.
+#
+# Many years ago Gwillim Law wrote that a good source
+# for time zone data was the International Air Transport
+# Association's Standard Schedules Information Manual (IATA SSIM),
+# published semiannually.  Law sent in several helpful summaries
+# of the IATA's data after 1990.  Except where otherwise noted,
+# IATA SSIM is the source for entries after 1990.
+#
+# Another source occasionally used is Edward W. Whitman, World Time Differences,
+# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
+# I found in the UCLA library.
+#
+# For data circa 1899, a common source is:
+# Milne J. Civil time. Geogr J. 1899 Feb;13(2):173-94.
+# https://www.jstor.org/stable/1774359
+#
+# For the 1911/1912 establishment of standard time in French possessions, see:
+# Société Française de Physique, Recueil de constantes physiques (1913),
+# page 752, 18b.
+#
+# European-style abbreviations are commonly used along the Mediterranean.
+# For sub-Saharan Africa abbreviations were less standardized.
+# Previous editions of this database used WAT, CAT, SAT, and EAT
+# for UT +00 through +03, respectively,
+# but in 1997 Mark R V Murray reported that
+# 'SAST' is the official abbreviation for +02 in the country of South Africa,
+# 'CAT' is commonly used for +02 in countries north of South Africa, and
+# 'WAT' is probably the best name for +01, as the common phrase for
+# the area that includes Nigeria is "West Africa".
+#
+# To summarize, the following abbreviations seemed to have some currency:
+#	 +00	GMT	Greenwich Mean Time
+#	 +02	CAT	Central Africa Time
+#	 +02	SAST	South Africa Standard Time
+# and Murray suggested the following abbreviation:
+#	 +01	WAT	West Africa Time
+# Murray's suggestion seems to have caught on in news reports and the like.
+# I vaguely recall 'WAT' also being used for -01 in the past but
+# cannot now come up with solid citations.
+#
+# I invented the following abbreviations in the 1990s:
+#	 +02	WAST	West Africa Summer Time
+#	 +03	CAST	Central Africa Summer Time
+#	 +03	SAST	South Africa Summer Time
+#	 +03	EAT	East Africa Time
+# 'EAT' seems to have caught on and is in current timestamps, and though
+# the other abbreviations are rarer and are only in past timestamps,
+# they are paired with better-attested non-DST abbreviations.
+# Corrections are welcome.

+# From Abdelrahman Hassan (2007-09-06):
+# Due to the Hijri (lunar Islamic calendar) year being 11 days shorter
+# than the year of the Gregorian calendar, Ramadan shifts earlier each
+# year. This year it will be observed September 13 (September is quite
+# hot in Egypt), and the idea is to make fasting easier for workers by
+# shifting business hours one hour out of daytime heat. Consequently,
+# unless discontinued, next DST may end Thursday 28 August 2008.

+# From Milamber (2020-05-31)
+# In Morocco (where I live), the end of Ramadan (Arabic month) is followed by
+# the Eid al-Fitr, and concretely it's 1 or 2 day offs for the people (with
+# traditional visiting of family, big lunches/dinners, etc.).  So for this
+# year the astronomical calculations don't include the following 2 days off in
+# the calc.  These 2 days fall in a Sunday/Monday, so it's not acceptable by
+# people to have a time shift during these 2 days off.  Perhaps you can modify
+# the (predicted) rules for next years: if the end of Ramadan is a (probable)
+# Friday or Saturday (and so the 2 days off are on a weekend), the next time
+# shift will be the next weekend.
