0 minutes of daylight is gained from daylight savings time.

60 minutes is how much is shifted to later in the day.

I completely agree with this point. But using the conventions of "business hours" to drag people out of bed earlier allows them to get off work earlier and utilize the daylight they already have more fully. But it is without a doubt a psychological shell game.

There is no amount of daylight I can utilize as I’m not a farmer. Where the sun is has almost no bearing on my life but forcing me to suddenly wake up an hour earlier certainly does

[–] [email protected] 1 points 9 months ago

Sounds like somebody needs a soma holiday

[–] [email protected] 9 points 9 months ago (1 children)

The main problem is that the old 9 to 5 business hours puts three hours before noon and five after, which is why DST moves time later in the day.

Just change 'business hours to' 8 to 4 and call it a day. or 7:30 to 4:30 if it needs to be 8 hours plus lunch.

Logic and sense? Get out of here! Obviously what we need to do is make daylight saving time permanent year round!

/s, if that wasn’t obvious

[–] [email protected] 0 points 9 months ago

Every time I get in an argument with someone who wants year round daylight savings time, they think it happens in the winter.

[–] Cethin 4 points 9 months ago (1 children)

I don't know what exactly this is measuring, but the amount of daylight in a day does change throughout the year. If this is measuring the amount of daylight gained from dead winter to the shift, then it actually is increasing the amount of daylight.

"In addition to" makes it sound like it is being added.

[–] [email protected] 1 points 9 months ago (1 children)

It's definitely in addition to dst, look at the southern states.. the blue/cyan is 50 minutes (plus 60)

[–] [email protected] 2 points 9 months ago

If you are counting the shifting of 60 minutes to the evening, then you o ly add half of the increase in actual daylight per day to the evening because that is split across noon. You don't add the whole of both to the evening.

It doesn't make sense to add those two numbers together in any context.

[–] [email protected] -4 points 9 months ago (1 children)

Useful daylight is gained. Daylight before I wake up is useless to me. Daylight in the evening after work is useful.

[–] [email protected] 5 points 9 months ago

Making the sun come up later screws with my sleep schedule and so I don't get the benefit of the later light.

Daylight when I'm tired is useless to me.

Can't express how happy I am to finally be coming out of the deep dark. Seattle is a lot better in the summer when the days are like 16 hours long. I love it.

[–] [email protected] 8 points 9 months ago

Omg yes. Seattle’s eternal summer dusks are idyllic.

We live in an age now where everyone could potentially sync up with "sunrise" as a floating value.

Your alarm clock will wake you up at sunrise +0.5h (if the sun doesn't).

Work starts at sunrise +2h.

Daylight savings time no longer exists.

Everything is good.

[–] [email protected] 13 points 9 months ago (1 children)

Take out the "work starts at sunrise +2h" for everything to be good. Work is overrated.

[–] [email protected] 1 points 9 months ago

I mean, sure, in a perfect world I would work at my own convenience, but baby steps I suppose.

[–] [email protected] 6 points 9 months ago (1 children)

That probably would work well for those closer to the equator.

But for those in the 100 minutes zone of this map that would mean going to work at 6:30am in the summer (assuming we are using civil twilight as "sunrise"), and 9:30AM in the winter which is much more of a swing than daylight savings puts on us, but at least it is a gradual one.

For those above the Arctic Circle, they just work 24/7 for a couple of weeks in the summer but get a similar time off in the winter ;)

[–] [email protected] 1 points 9 months ago

I don't really see that 3 hour gradual swing as much of a problem. Evolution set sunrise as our "start" by default. Shifting to a more rigid structure leads to a lot of issues involving sleep and depression, so we really should abandon it.

[–] [email protected] 15 points 9 months ago (2 children)

There's a slash through the middle of the country that will lose about 4 minutes of daylight in april

[–] [email protected] 2 points 9 months ago

Took me a minute lmao

Math enthusists cringe at the discrete bands tho

47* states*, most of Arizona has no DST although some of the reservations observe it

[–] [email protected] 11 points 9 months ago (1 children)

DST does not change the amount of sunlight. Just shifts the time frame.

[–] [email protected] 9 points 9 months ago* (last edited 9 months ago)

Yes, and refrigerators actually create more heat than cool.

[–] [email protected] 5 points 9 months ago (5 children)

Is that minutes per day, or total?

[–] [email protected] 7 points 9 months ago

Minutes per day between the first day and last day of March. I assume.

[–] [email protected] 3 points 9 months ago

Minutes per day. I.e. sunrise and sunset on Mar 31 are the indicated number of minutes farther apart than sunrise and sunset on Mar 01.

Cumulative and exponential actually 💩

[–] [email protected] 4 points 9 months ago (1 children)

Would be interesting to see it for a world map

[–] [email protected] 1 points 9 months ago

And as a slow vid.

[–] [email protected] 4 points 9 months ago (1 children)

You think that's crazy. Think of what it must be like in Alaska!

[–] [email protected] 5 points 9 months ago

About 165 minutes for Anchorage... For reference, Helsinki is also 165, Glasgow is 135, London 120, even Milan is 95

Coming from anywhere in Europe the idea of somewhat balanced day lengths throughout the year sounds wild

But don't forget to awkwardly wrap it around country lines

[–] [email protected] -2 points 9 months ago (1 children)

Are these values inclusive of the 60 minute nonsense?

[–] [email protected] 13 points 9 months ago

I would say no, because no daylight is gained by switching from Standard Time to Daylight Savings Time. But even if we did gain an hour with the clock change, this graphic wouldn’t include it b/c that would mean the southern part of the graphic would imply that those folks lost 20 minutes of actual daylight over the month of not got a clock change to save them.
