Thank you for this information. In particular, the extended table of dates is incredibly helpful. Our codebase requires us to make reasonable predictions of date patterns into the indefinite future. Since all of the dates provided here match a similar pattern to the one used from 2016 to 2018 — that is, the Saturday before the last Sunday in March and October (or "Sat>=24") — that seems like a reasonable prediction for now, except these new clock changes will be at 02:00 on those dates. If the dates might leave this pattern at any point, again, please aim to provide as much notice as possible. While we write up this change… We do like to cite publicly-available sources for the data we distribute so that users can confirm the data for themselves. I understand this was a recent decision, so it may not be posted to your ministry's website yet. Could you kindly send along a public link to this decision or a similar announcement once it's posted? Thanks again. -- Tim Parenti

Does the government of the State of Palestine expect that these rules will continue to be used in 2027 and later years, or have they not made a decision on years after 2026?

Either way, we're better off assuming the rules will continue, as that's more likely than discontinuing. I installed the attached further patch, which changes the rules' form to more closely match the English-language summary that Heba Hamad gave today.
Dear Sir, the government of the State of Palestine doesnt make a decision on years after 2026 but MTIT will try to keep this rule after 2026 BR, في الأربعاء, أغسطس 31, 2022 18:22 EDT, Paul Eggert <eggert@cs.ucla.edu> كتب: On 8/31/22 01:25, Guy Harris wrote:

The illustration on that page makes it clear that the Arabic text is probably meant to say winter time starts with the value 2 am on Saturday 2022-10-29 rather than the switch to winter time occurs when summer time would have assumed the value 2 am on Saturday 2022-10-29 as it was wrongly interpreted in the proposed changes to Rule Palestine.

Ouch. My guess is just the opposite. That is, my guess is that the illustration[1] (attached) in [2] is wrong, and I guess that the text is correct. That is, I think the illustration should show the clock moving backward from 2am to 1am, not from 3am to 2am. Heba Hamad, can you please confirm which is correct here? The illustration or the text? The text matches the document you already sent us. Thanks. [1]: https://mtit.pna.ps/Content/imgs/news/-8585393378987544401IMG-20220903-WA000... [2]: https://mtit.pna.ps/Site/New/1453
Thanks for the information. It is good to have predictions for several years in advance, as it can take some time for this information to propagate to cell phones and computers. The attached proposed patch predicts similar transitions after the year 2026, as that seems more likely than no transitions. Although the announcement doesn't say how transition dates are calculated, the dates through 2026 are consistent with Palestine springing forward at 02:00 on the first Saturday on or after March 24, and falling back on the first Saturday on or after October 24. If this is not the intended rule please let us know, since our software is rule-based for predictability. As Tim mentioned, it'd also be good to have a URL referring to a public announcement of the change. In the meantime the attached proposed patch refers to an archived copy of the decision of the Council of Ministers that you emailed to us. It looks like we'll need a new tzdb release in the not-too-distant future, since the current release is wrong for Palestinian timestamps for about one day on October 28.

I.e., while we *could* add specific rule lines for each of those years, if we can, instead, have a general rule line that starts in 2023 and continues on, which means that if 2027 continues the pattern, the Palestinian government wouldn't need to inform us of the behavior for 2027, and we wouldn't have to update the file in 2027, and so on for further years after 2026. That's what Paul's patch does - adds a general rule, so we would need an update from the State of Palestine only if 2027 or 2028 or... *doesn't* follow the pattern.
