I instead suggest that we make the DST shift 12 hours. [[Special:Contributions/172.68.1.190|172.68.1.190]] 15:16, 25 October 2023 (UTC)

:I have better idea: What about observing the DST change in fall but ignoring the DST change in spring? -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 21:18, 25 October 2023 (UTC)

::Even better: 12 hours backwards shift in fall, no shift in spring. Sure, it would lead to confusion, but it’d also be really funny. [[Special:Contributions/172.68.58.135|172.68.58.135]] 04:59, 26 October 2023 (UTC)

The terrorist plot wasn't thwarted by this kind of proposal. It was just due to the fact that DST laws differ between countries. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 15:31, 25 October 2023 (UTC)

: The Palestinian terrorist plot on 5th September 1999 definitively was.  One group of terrorists switched to ST as decided by authorities, while other refused to and used DST. [[User:Abukaj|Abukaj]] ([[User talk:Abukaj|talk]]) 16:36, 25 October 2023 (UTC)

When I read the comic, I applied it to this upcoming clock change which would turn the clocks back to "standard" time. Thus the ironic joke is that if you don't like daylight savings time then don't change your clocks, so you are then stuck in daylight savings time forever.

::Added a (larger than intended) paragraph to this end. On the presumption that, at each biannual clock-changing moment, the policy translates the current feelings of the person into whether they ''must'' add/remove an hour (even opposite to what they think they should do).
::If I had realised that it'd be so lengthy an 'explanation', before starting to edit, I'd have maybe added a Trivia-like section, or just inserted the ideas within it down here in Talk.
::I do believe that Black Hat's part in the announcement indicates an intentional multi-tiered chaos of this kind (rather than if a Cueball, where it might indeed be only "on/not-on DST" for the relevent half the year for single-order chaos).

:Actually, a year ago they were all set to skip that fall one, it was a done deal, so we WOULD have been permanently on Summer Time (which is what I see as Standard Time, it always seems like the point of this is to maximize daylight in the winter when there's less of it). I only found out THAT NIGHT that the decision was overturned. I'm still hoping for this year, but I've heard nothing so I doubt it. :( [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 05:02, 29 October 2023 (UTC)
:::I remember this argument from before. The daylight one saves is the 'summer morning daylight'. By reverting to non-DST you don't save anything, you just make the mornings less dark than they would abnormally be. (Indeed, this morning I was out and about before 7:30AM (GMT) and had a nice bright day that ''wasn't'' (unlike during recent BST-ruled mornings) darker than they ought to be just because most people want a >4:30PM 'daylight' rather more than a <7:30AM one).

::::...Except summer doesn't need any "help", the days are longer, plenty of daylight to go around. :) It's the short short winter days which - if anything - require help to make the most out of whatever little daylight there is. And like I said, last year they were about to make Summer Time permanent, we would have stayed on THAT time, not the Winter Shifted time.

:::::You are right (as well as wrong). Borrowing from Peter to pay Paul. Of course Peter is flush, in summer, and doesn't need so much morning light, so Paul can entertain himself for long evenings and everybody's happy (certainly more happy, in total, than if Peter just frittered away his spare cash every morning, long before he needs to go to work!
:::::In the winter months, Peter might already feel the pinch. Not only are the days ''naturally'' drawing closer, but someone's decided that he doesn't really need as much of the (already limited) daylight as he started with. Paul's getting ''some'' more evening (still gets dark early enough, though, depending on latitude). Marginal gains for him, if he's lucky, and good for him. But more-than-marginal losses for the other guy, and always net losses because you can't actually argue against the local astronomy.
:::::The decision to have "summer-in-winter" (with or without "double-summer", also) just rearranges the deckchairs a bit. If you're on the Titanic, the best you can hope for is that this means it's easier to run straight out and onto the rather limited number of lifeboats (when you need to), but it's more of a cosmetic exercise when you can't (or needn't) get onto one.
:::::Now, if schools/workplaces operated on something like "from one hour after sunrise", instead of tied to crepuscularly-agnostic clock-time (of whatever shift from absolute astronomical timings), we could stop arguing the rest of the point and just deal with what people 'deem' most appropriate. And there's no such thing as "winter shifted time" (unless you do Wintertime+1 to keep with/keep pace with the shift you made for summer). It's only "winter ''un''shifted time", as I note has been said before... Give or take how far from your longitude's 'natural' noon is away from the clock-noon your country/region has adopted. (e.g. China, wide in longitude, one single timezone throughout, but to some extent ''every'' TZ's fringes, even if that's just around half an hour of 'cosmic shift', before politics adds or removes anything else.)

== Average 39 minutes ==

While this figure makes sense (rather than 30 minutes) it was still slightly unexpected at first; as DST has a duration of 238 days, the average year-round time would be 238/365 hours ahead of Standard, or 39 minutes and 7.4 seconds.
(Or, to factor in that a leap day occurs in 97 of every 400 years, 238/(365 ⁹⁷⁄₄₀₀) = 39 minutes and 5.8 seconds)

[[User:SomeDee|SomeDee]] ([[User talk:SomeDee|talk]]) 15:23, 25 October 2023 (UTC)

I was wondering where that number came from... trust him to use the most absurd metric possible for averaging, instead of, for instance, the average deviation of sunrise, solar noon, or sunset... or even their earliest or latest times. - [[Special:Contributions/172.68.2.102|172.68.2.102]] 17:17, 25 October 2023 (UTC)

I haven't calculated for myself what US DST would actually average out at (presuming Randall is correct), but 'average year-round clock offset' for Europe (inc. UK, at least currently) would be different because it starts ''one week earlier'' (last Sunday in March, rather than first Sunday in April, if I remember the months right). One fifty-twoth of an hour (going straight to how the weightings change, rather than calculating the full averages in my head anew) is going to be slightly more than a minute of difference, so probably in the realms of UTC(+regional hourly shift)+40minutes. Maybe even +41 if it rounds off over into the ''next'' minute. [[Special:Contributions/172.71.242.175|172.71.242.175]] 22:15, 25 October 2023 (UTC)
:It also ends two weeks earlier, (Middle of October instead of first week of November), so I'm really not sure on the actual difference. I just know that it's a headache for a couple weeks on either end for multinational meetings. [[Special:Contributions/172.70.100.194|172.70.100.194]] 16:26, 26 October 2023 (UTC)
::One week early. Had to check, as it was identical (at one end or other, but an adjacent weekend at the other end or one) back when it mattered to me; might have changed in 2007.
::Last Sunday in October here (will change in about 24 hours from posting this, for me), first Sunday in November for US. So that's a week at each end, and approx 2 minutes difference on the average Randall'd have to use on his next visit.

== Major health ==

> "''has been found to cause major health problems''"

Citation needed.

One reported factoid: 
''"..a group of U.S. researchers ...determined that heart attack risk jumped 24 percent the Monday after switching over to daylight saving time. .....dropped 21 percent on the Tuesday after the fall time change."''
https://www.heart.org/en/news/2018/10/26/can-daylight-saving-time-hurt-the-heart-prepare-now-for-spring
24% in fall, 21% in spring, suggests 3% net, which is more likely margin-of-error than major-problem.

"has been suggested" or "controversial" but not "has been found".

== Personal Inclination == 

I haven't changed clocks for DST in years. That system is garbage; it doesn't even fall on obvious days. When someone says a clock is off, shrug & say "That's debateable. This one's right year-round, how often do you have to set yours?"

: Huh? So you're an hour late or early for half the year? [[Special:Contributions/172.70.215.9|172.70.215.9]] 21:29, 25 October 2023 (UTC)
: What would be "obvious days"? The equinoces, I suppose would be the astronomical absolutes, but they vary by several (calendar) days, and does this mean that clocks change at their hour, minute and second, regardless of whether in the middle of a week ''and workday''..? Also, the benefit (or otherwise) of any given date changes by latitude. And on what sleep cycles (early mornings or late evenings) any given person has. Equinox-nailed switchovers (or even tied to month-endings, say March 31st 24:00 to September 30th 24:00) just don't help much more (maybe less) than current versions. Heck, it's arbitrary, as might be many other choices, but it seems to keep disruption to the minimum (during changeover), and if the redistribution of hours isn't to your liking (a farmer may get up at/before dawn ''every day'', regardless of what pesky clocks say, 'cos animals and crops don't 'adjust' by our method) then that's up to you. But I bet some things will change around you and you at least need to mentally adjust to what time everyone around you decides it is. [[Special:Contributions/172.70.85.232|172.70.85.232]] 23:58, 25 October 2023 (UTC)
:Clock time is itself arbitrary. Why 12 hours twice instead of, say, 10 hours for one cycle per solar day? The answer boils down to "In ancient times, it was easy to divide 12 into fractions in your head. Also, counting hours at night was harder (no sundials) and less important (because pre-electricity, most people just slept)." [[User:Nitpicking|Nitpicking]] ([[User talk:Nitpicking|talk]]) 03:28, 26 October 2023 (UTC)
::Easy in modern times, too, since 12, 24, and 60 are {{w|highly composite number}}s and 10 can't even divide into thirds or quarters&hellip; <span style="background:#0064de;font-size:12px;padding:4px 12px;border-radius:8px;">[[User talk:AgentMuffin|<span style="color:#f0faff;">~AgentMuffin</span>]]</span> 04:25, 26 October 2023 (UTC)
:: You can thank the Babylonians and their base 60 number system for both modern time divisions AND the system of degrees. It's been argued (not sure if proven) that the reason for that was exactly as agent muffin said: It's highly divisible to common fractions of 1/2, 1/3, 1/4, 1/5, and 1/6, which coordinates well with regular polygons up to the largest that tiles a plane. Personally I think it came about the other way around (multiples of 3/4/5) but semantically it's the same - [[Special:Contributions/172.68.2.93|172.68.2.93]] 20:51, 26 October 2023 (UTC)
: I also haven't changed most of my clocks for DST in years. Most of them change themselves; my digital watch, kitchen wall clock and living room mantelpiece clock are radio-controlled, while my computers and iPad use NTP. Even my central heating system adjusts itself, but it doesn't use an external time source, so while it needs manual adjustment, it's not for DST. That just leaves my car, my oven and my telephone, none of which use an external time source so need regular adjustments anyway (or they would if I actually used them to tell the time). --[[Special:Contributions/172.69.43.241|172.69.43.241]] 10:27, 27 October 2023 (UTC)

A bit of a seasonal puff-piece 'news article', perhaps, but [https://www.bbc.co.uk/news/uk-67243110 a brief BBC item about the upcoming change] might appeal to those reading this.

Why don't we just get one time for everyone worldwide that stays the same all year? I, for one, wouldn't care if noon was at 4:17 instead of 12:00! Even at the risk that mathematicians and astronomers will hate me for the following sentence: get real, damn it, it's just numbers! [[User:PaulEberhardt|PaulEberhardt]] 17:62, 32 October 2023 (according to my watch)
:Well, that's just UTC (or UT1/close equivalents). Though {{w|Timekeeping on Mars#Coordinated Mars Time|I can think of a different system}} we could use... [[Special:Contributions/172.69.79.143|172.69.79.143]] 20:35, 28 October 2023 (UTC)
::No, not UTC... Paul means when it's noon here in the Eastern part of North America, it's noon in California, noon in the UK, noon in Europe, noon in Japan, noon in Australia, etc. And I must say, not a bad idea. WHY does "noon"/12PM have to be the time that the sun reaches its peak? Who cares? THIS way you say a time, everybody in the world knows what time it is, no timezone conversion, no accounting for DST, super clear. :) [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 05:16, 29 October 2023 (UTC)
:::Paul doesn't explicitly suggest that worldwide-Noon should be the astronomical noon ''anywhere in particular'', let alone Eastern NA. Just 'somewhere'. Now, obviously it'd be most logical to choose somewhere significant... Maybe Washington time (because of Americocentricism) or Beijing (well, they've got the experience putting loads of people into one 'wide' timezone), or Delhi (now have pipped China over the issue of "most population covered", or Moscow (geographically most contiguously wide-spread, though even internally they'd alreadu have more anomolies than China has now), or... well, since London beat Paris in the battle to being the Prime Meridian for the world then ''obviously'' it'd be GMT or UTC/UT0/UT1/UT1R/UT2 (take your pick, according to what you value most about the 'standard'). Or maybe you'd prefer Kathmandu (UTC+05:45... because... why stick to whole-hour offsets?). [[Special:Contributions/172.71.178.179|172.71.178.179]] 18:30, 29 October 2023 (UTC)

One time worldwide is a pants idea.  Not because some people would be going to bed at 9 a.m., that's quite OK.  But because when you pass through midnight, the date changes, as does the day of the week.  You're working away merrily during (your) mid-morning on Friday 1st of Umptober, when suddenly midnight arrives and from now on you are on Saturday 2nd.  Oops, it's now weekend! [[User:MalcolmStory21|MalcolmStory21]] ([[User talk:MalcolmStory21|talk]]) 19:52, 29 October 2023 (UTC)
:If that's a problem (doesn't sound like it necessarily need be), it's balanced by having the early morning off (the weekend) and then it becoming Monday 4th and business as usual again.
:But all it needs is for some soft of 'shiftworld' (like the scenario in {{w|Dayworld}}, but spread around/overlapping around the day, not around/separate across the week), where there's a 24/7 (or at least a 24/5) economy 'serviced' by whoever wishes to be awake during whatever hours suit them (by actual daylight) or find expedient on a supply-and-demand basis. Currently, businesses open roughly aligned to daylight hours (to varying degrees) and they ''still could'', just with workers not doing a "9-to-5" job but perhaps a "3-to-11" or "12-to-8" or whatever. If it's a remotely-workable service industry, then you will (as you can now) be serviced by someone working half a world away in inconvenient hours that are convenient for you (or convenient hours that cover times that would be otherwise inconvenient to those local to you).
:If you actually need something like a post-midnight hairdresser (because that's the only time ''your'' particular work commitments let you fight back against such interminable perils of growing head-hair), it doesn't matter whether that's 'real' midnight or 'global' midnight because at least one guy/gal with the scissors should be able to mesh accordingly with your own schedule in a way that a current daytime-stylist might not at all be easily available for a current daytime-officeworker unless they're a weekend worker (and you are not), you can get a few hours off work or they're equipped to visit you at your desk.
:By being 'tied' to a global time, it just allows (with the right basic employment incentives and protections, naturally; which are obviously lacking in many situations right now, so would also constitute an improvement) a degree of flexibility that blindly subscribing to your local time really doesn't.
:...well, we're surely already talking about a conceptual world in which such massive reorganisation is even possible. Going the extra few steps to make it ''work'' isn't that much more of a stretch, I'm thinking. [[Special:Contributions/162.158.74.25|162.158.74.25]] 22:49, 29 October 2023 (UTC)
::I'm sure he just picked "noon" as an easy time to pick on, obviously noon everywhere means 1pm is 1pm everywhere as well, 2pm is 2pm, etc. Also, living in North America myself, I find "America-centric" seems to be Eastern time/New York City/Miami, not Western like the state of Washington (of course, you might mean the TOWN of Washington, D.C., which I think is indeed Eastern, LOL! Might explain why the America-centricity of the time zone, I never thought of that. I find it ridiculous that they have two Washingtons like that). I didn't go so far as figuring WHAT time zone should win (and the "4:17" makes me feel he didn't either), but it seems like there'd be no other choice than Greenwich Mean Time, as being the current time zone baseline. I DID/we did forget the midnight/date change aspect, that is of course what makes this all fairly necessary. Oh, and I avoid multiple paragraphs on here because of stuff like what you did: You forgot to indent your second paragraph, so they looked like separate comments, I was about to reply to only the first when I spotted what happened.

The comment ''after'' the unsigned one (browse "next"ward for it, on that link) was a properly-signed 'virgin unindented' comment by someone else (or when they logged in), justifiably without indentation.
