Talk:Daylight saving time by country

Table colors mismatch data/maps

At this present time, the data provided by the map images does not match that of the table. Just to pick one example: the table states that the country of Brazil observes daylight savings time for both Northern and Southern hemispheres. While the "Northern" part of this makes no sense given the geographic location, the map images do not support current observation of daylight savings time. — Christopher, Sheridan, OR (talk) 22:22, 13 March 2021 (UTC)

In revision of my previous text, the hemisphere colorations are confusing. The map images color mark countries as they utilize daylight savings time. According to the maps, Brazil previously used DST, but presently does not, which is verified by the table. However, while the map images display Brazil in light gray, the table displays Brazil in orange as if it observes DST, even though the text adjacent to it refutes this. I therefore propose that Brazil in the table, be changed from orange to light gray. I further propose that the entire table be examined for similar miscolorations. — Christopher, Sheridan, OR (talk) 22:42, 13 March 2021 (UTC)

add line in the table

hi how can i add the line in the table of " oservance as of 2021 " for ( Chatham Islands new zealand observe Daylight saving time from last sunday of september at 2h45 to first sunday of april at 3h45 and the Easter island observe DST from first sunday of september at 22h00 to first sunday of april at 23h00 at last thank you than bye . --Yazid6 (talk) 08:42, 23 September 2021 (UTC)

@Yazid6: The Chatham Islands start and end DST at the same UTC time as the rest of New Zealand, and Easter Island starts and ends DST at the same UTC time as the rest of Chile. The table shows the times in New Zealand and Chile with a UTC offset, so they already include the equivalent local times in the other islands with different UTC offsets. There is no need to add the islands in separate lines. Heitordp (talk) 08:00, 26 September 2021 (UTC)

Jordan

@Yazid6: The time switch in Jordan is specified as midnight 24:00 on the last Thursday in February. This is not always the same as midnight 0:00 on the last Friday in February. For example, in 2024, the last Thursday in February is 29 February, and the last Friday in February is 23 February. The time switch will be at 24:00 on Thursday, 29 February 2024 (equivalent to 0:00 on Friday, 1 March), not 0:00 on Friday, 23 February 2024. Heitordp (talk) 11:07, 23 February 2022 (UTC)

I reverted the change. Guy Harris (talk) 18:02, 23 February 2022 (UTC)

Chile

@Yazid6: The time changes in Chile are specified as 24:00 on the first Saturday in September and April. This is equivalent to 0:00 on a Sunday, but it can be the first or second Sunday in the month, depending on the year. So it's better to specify it as 24:00 on the first Saturday, as stated in the decree, as it works for any year, instead of trying to convert it to 0:00 on a Sunday.

hi thank you for your answer Yazid6 (talk) 17:02, 8 April 2024 (UTC)

Make the table sortable?

It's really hard to parse in the current format 82.14.222.80 (talk) 14:49, 3 November 2024 (UTC)

I made the table sortable by adding sort values representing the earliest date and time, in UTC, of the DST changes in each area. But the exact order can vary slightly, for example in some years the DST end date in Egypt (last Thursday in October) occurs before Europe (last Sunday in October), and the DST end time in Cuba (05:00 UTC) occurs before parts of North America (04:00 to 11:00 UTC).

Morocco and Ramadan

Hey all, so I'm curious, why is Morocco not included in the table and/or map? The actual note underneath mentions they abandon DST for a month during Ramadan, so surely it should be listed on the table & map as still changing their time zone? I just wanted to enquire before anything was changed. Many thanks Essexman03 (talk) 17:36, 6 October 2025 (UTC)

Daylight saving time, also known as summer time, is the advancing of clocks during a part of the year that has more daylight, including summer. Until 2018, Morocco observed UTC as its standard time, and observed actual DST, advancing 1h from March to October, with a suspension of DST during Ramadan if it fell during that part of the year. In 2018, Morocco changed its standard time to UTC+1 and stopped advancing 1h for part of the year, but it still reduces 1h during Ramadan. The TZ database records it this way, as a temporary reduction.

To consider Morocco as observing DST, you'd have to consider its standard time as UTC, and advancing 1h from after Ramadan until before Ramadan of the next year. For consistency, it would also have to be changed in the article time zone and other maps. But I don't think that this is the best way to describe Morocco, since UTC+1 is used for almost all year, and the change to UTC is not related to daylight or summer.

If it's useful to add Morocco to the table here, I suggest changing the table header, the paragraphs and the map captions to refer more generally to annual time changes instead of DST. Then Morocco can be added, with the start date before Ramadan, end date after Ramadan, shift of -1h, and colored on the map above the table. But on the map at the top of the article, Morocco can't be colored either blue (northern summer) or orange (southern summer). It would need a different color, or just remain gray.

morrocco observes DST all year and only turns back when Ramadan starts(depends what month)

Last Time Morocco Used DSTlink is last time morroco used DST American Angel1 (talk) 17:35, 8 April 2026 (UTC)

"DST but we turn the clocks back during Ramadan" isn't the same thing as "permanent DST". "Permanent DST" means "the clock is one hour ahead of the standard time for the time zone, and is always there, "permanent" meaning "continuing or enduring without fundamental or marked change", "lasting or continuing for a very long time or forever : not temporary or changing", etc. Guy Harris (talk) 18:30, 8 April 2026 (UTC)

Even if, they still don't use DST besides turning it back an hour for Ramadan so putting it on this page would be useless since someone would have to keep changing the date for the turning back and forth since ramadan doesn't fall on the same month each year.
