I'd be in favour of going one hour ahead of savings time 🙂 Sunrise would be at 9:45am tomorrow, but sunset would be at 6:40pm

That's pretty intuitive. Why can't we all just set our own preferred sun times at will depending on our mood? I mean, gone are the days when that Indian chief appears on the TV screen all of a sudden. Why do you care when my noon hour is? This is progress. Get with the times, eh. 😴

Around here at this time of year the noon sun is about where it would be at 2 - 3PM in the early summer, and it is dark by 4:30PM. It would be nice if we could just advance the clocks by an hour and stay there year round. I don't care exactly where the sun is at noon, I do care about the sun coming up at 5:30AM and setting at 4:30PM - it is gloomy enough around here in the winter as it is, the extra waking hours daylight would be very welcome as would less light in the 2 - 3 hours before I have to get up.

So a close friend took me to task for grossly exaggerating in my previous post and stated clearly and authoritatively that what I described is impossible. He is of course right, but that is what it feels like to me. Regardless, I still want the clocks forward an hour.

Here is today's meridian time. I generally walk between 1 - 2PM, but even a bit earlier the sun is noticeably past meridian. A 7:03AM sunrise is almost as late as it gets here, and in a month or so it will be rising considerably earlier, and the predawn even this time of year is pretty extended around here.

Sleep scientists want to keep us on standard time:
"It is the position of the AASM that the U.S. should eliminate seasonal time changes in favor of a national, fixed, year-round time. Current evidence best supports the adoption of year-round standard time, which aligns best with human circadian biology and provides distinct benefits for public health and safety."

I’m against it. Why? Because I work in outdoor drama. DST means that darkness comes an hour later than it should. The show still has to start at a decent hour for the kids, so the first act is done in the daylight for much of the summer. Really ruins the dramatic effect of a bright stage in the summer night.

In fact the state of North Carolina held off DST for years because of the importance of its two big outdoor dramas. But that was long ago.

So I don't get the problem here. Who would be opposed to perpetual saving time? What is the purpose in 'falling back'? How is leaving it forward not best all year round? It's bewildering why after coming up with the idea one would then cancel it for half the year. Weird.

I'm in favor of stopping the continual change but, how is it perpetually saving time? Just because the name is "daylight savings time" doesn't mean it actually saves time. In some areas it would be dark until near 9 in the morning in the middle of winter. Little kids walking to school in the dark? I believe the states that have already stopped doing it just did away with DST, not made it permanent. .
If you want to enjoy more sunlight in the summer, just get up earlier.

Actually that'd be regress. The world used to run like that. Every town had the clocks set to noon at solar noon. Then the railroad came along and ruined everything. Somehow it became practical to agree on when the train left Chicago...

I spent a year working in a circadian lab as part of my psychology degree. My advisor had some interesting data to share. If you look across the US there's a gradient in the prevalence of various diseases (cancer, heart/lung disease, stroke, etc.) that's strongly correlated to how far in a state you live from the time zone boundary. Time zone boundaries aren't straight lines and neither are state lines, so you'll find places that are closer to 'standard' time and other places that are closer to 'daylight saving time'. The parts that are closer to 'daylight saving time' have higher rates of disease. That piece of the puzzle seems missing from the public debate.

Instead the public debate centres on convenience factors.

We voted in Alberta on whether to adopt permanent daylight saving time and it was defeated by a pretty narrow margin. Saskatchewan is on permanent standard time. I'd love to get rid of the time change, but let's stay on standard time for better health.

That's very interesting. Was causality established? I'm wondering what could be the causes. Mental health? Vision related?

Sure, I agree. I just find it odd to implement it and then reverse it again which seems counterintuitive and obstructive.

Very interesting you should bring that up. My daughter moved down to Thunder Bay from Whitehorse because the rate of diabetes among the white population is catching up to the historically more prevalent incidence among the indigenous population and it's being questioned whether it's due to northern sun times. She wanted to safeguard her five children. I wonder how that may correlate to other northern climates
