Though it can be hard to tell reading a diff, that particular link is from the pre-existing comment introduced in March 2023 and does not relate to the recent action.

Hi Tim, My fault, thinking, was the official link for the next change in 20th Sep. 2026 (false: it's 2023). The website for this URL isn't official https://www.moroccoworldnews.com/2026/06/325034/confirmed-morocco-to-restore... So today I tried to find official news about the decree, but I cannot find it in MMSP.gov.ma or SSG.gov.ma (official for decree). The changes have been decided yesterday, but probably some day to publish officially. Regards, Milamber On Thu, Jun 25, 2026 at 7:26 PM Tim Parenti <tim@timtimeonline.com> wrote:

From my Google searches on news coverage of the topic, it seems *incredibly* recent — within the last few hours — and since many governments batch their publication/gazetting of decrees, it is not entirely unexpected that it's not on an official site quite yet. One nice detail which can bolster our confidence is that many of these news reports give the decree number, 2.26.530, which will be straightforward to verify. -- Tim Parenti

Yes, it'll be helpful to cite the decree, assuming we can get a URL. We now have only one area (Palestine) with DST changes using the Islamic calendar and one area (Ireland) with negative DST. As far as I know Morocco was the only place that ever did both simultaneously.
The decree was published in the official gazette of 29 June 2026: https://www.sgg.gov.ma/BO/AR/3111/2026/BO_7521_Ar.pdf
