- # 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
- #
- # 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 Paul Eggert (2007-08-17):
- # For lack of better info, assume the new rule is last Thursday in August.

- # 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.
