Hi! Here's some "resmi gazete" links for those years. http://www.resmigazete.gov.tr/arsiv/14539.pdf (page 24) 1973-06-03 01:00 -> 02:00 1973-11-04 02:00 -> 01:00 http://www.resmigazete.gov.tr/arsiv/14829.pdf (page 1) 1974-03-31 02:00 -> 03:00 1974-11-03 02:00 -> 01:00 http://www.resmigazete.gov.tr/arsiv/15161.pdf (page 1) 1975-03-22 02:00 -> 03:00 1975-11-02 02:00 -> 01:00 http://www.resmigazete.gov.tr/arsiv/15535_1.pdf (page 1) 1976-03-21 02:00 -> 03:00 1976-10-31 02:00 -> 01:00 http://www.resmigazete.gov.tr/arsiv/15778.pdf (page 5) 1977-04-03 02:00 -> 03:00 1977-10-16 02:00 -> 01:00 1978-04-02 02:00 -> 03:00 (not applied, see below) 1978-10-15 02:00 -> 01:00 (not applied, see below) 1979-04-01 02:00 -> 03:00 (not applied, see below) 1979-10-14 02:00 -> 01:00 (not applied, see below) http://www.resmigazete.gov.tr/arsiv/16245.pdf (page 17) This cancels the previous decision, and repeats it only for 1978. 1978-04-02 02:00 -> 03:00 1978-10-15 02:00 -> 01:00 (not applied due to standard TZ change below) http://www.resmigazete.gov.tr/arsiv/16331.pdf (page 3) This decision changes the default longitude for Turkish time zone from 30 degrees East to 45 degrees East. This means a standard TZ change, from +2 to +3. This is published & applied on 1978-06-29. At that time, Turkey was already on summer time (already on 45E). Hence, this new law just meant an "continuous summer time". Note that this was reversed in a few years. http://www.resmigazete.gov.tr/arsiv/18119_1.pdf (page 1) 1983-07-31 02:00 -> 03:00 (note that this jumps TZ to +4) 1983-10-02 02:00 -> 01:00 (back to +3) http://www.resmigazete.gov.tr/arsiv/18561.pdf (page 1 and 34) At this time, Turkey is still on +3 with no spring-forward on early 1984. This decision is published on 10/31/1984. Page 1 declares the decision of reverting the "default longitude change". So the standard time should go back to +3 (30E). And page 34 explains when that will happen: 1984-11-01 02:00 -> 01:00 You can think of this as "end of continuous summer time, change of standard time zone". http://www.resmigazete.gov.tr/arsiv/18713.pdf (page 1) 1985-04-20 01:00 -> 02:00 1985-09-28 02:00 -> 01:00

Excuse me for the subject. It was meant as a response to early discussion re: Turkey rules.

It would also be good to know the law or decree reference and the date enacted, if present on those pages, as they are not obvious to non-Turkish speakers. -- Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada This email may be disturbing to some readers as it contains too much technical detail. Reader discretion is advised.
Can you please look into the question whether there was double daylight saving time in 1940/41 as claimed by http://www.astrolojidergisi.com/yazsaati.htm with footnote 1 and related ekler 3,4,5 ? It needs a Turkish speaker with understanding of time zone issues to clarify that.

Thank you. This is also what I find: NO DST in 1979,1980,1981,1982 Besides resmigazete, I have also started to search newspaper archives. http://gazetearsivi.milliyet.com.tr (Milliyet) is free and searchable. Even without speaking any Turkish, I can confirm: The time change on 2 April 1978 (begin of DST) is announced on page 1 the day before. There is no such time change announcement on a further date in 1978, 1979, 1980, 1981, 1982. I have alaways checke the papers on the supposed data, and the day before. My search keyword is saat I find the next time change announcement in the paper on 30 July 1983, for the change on 31 July 83, 2:00 am. On 12.08.19 19:37, Kıvanç Yazan wrote:

Thanks for all that work in tracking down legal citations for Turkish time from 1973 through 1985. I installed the attached patch to tzdb, to incorporate those citations. This doesn't affect the data, since the citations agree with the Oya Vulaş table that we just got data from, but it's better to cite the original sources than to go indirectly via Oya Vulaş.
