Indiana observes DST statewide since 2006.

What they tried in 1974 was year-round DST. Standard time doesn't darken mornings.

By 2040, ~40% of the images from Hubble Space Telescope, and more than 96% from new and future space telescopes like SPHEREx, ARRAKIHS, and Xuntian will be contaminated by internet satellite constellations.

Winter driving is challenging. When nature gives 9 hours of daylight, neither 8am nor 4pm need be dark.

That would trade one issue for another: darker mornings as in 1974, still problematic. Both AM and PM light are important, and standard time (observed year round in many states until 1966) balances them fairly.

New Hampshire is too far west for Atlantic time.

Sleep doctors’ orders: Use standard time 365 days a year It’s time again for clocks to “spring forward” to daylight saving time. Learn why physicians are saying that tradition should stop.

That would put January sunrises as late as 8:18, not good for safety or health. Doctors recommend standard time instead.

As of Dec 1, three others have been discovered.

Sorry, that's false. Mean solar noon along the OH/PA border is 12:22 PM EST or 1:22 PM EDT.

At this time of year our eccentric orbit and oblique rotation make the Sun appear to run a few minutes earlier than average (equation of time). In January it runs later.

At 4 in Boston the sun is still up.

The rotation relative to the stars is as steady as you'd expect. Our eccentric orbit and oblique rotation make each solar day a few seconds shorter or longer than the 24h average, accumulating so that the Sun runs ~16 minutes early in November and ~14 minutes late in February.

Equation of time - Wikipedia

The axial tilt is part of it. Another part is the Earth's eccentric orbit around the Sun.

Part of the solar analemma from late October through late January, showing the sun setting earlier around December 7 than at the solstice.

The Sun runs a few minutes early at this time of year due to the Earth's oblique rotation and eccentric orbit. The analemma near sunset at 40°N shows how the Sun is lower around Dec 7 although it's farther south at the solstice.

That would be a result of having DST year round as in 1974. Standard time is safe in all seasons.

AI Slop Recipes Are Taking Over the Internet -- And Thanksgiving Dinner Food bloggers see traffic dip as home cooks turn to AI, inspired by impossible pictures

NEW: AI “recipe slop” is overrunning search and social. Food creators say Google’s AI Overviews and glossy fake food pics are drowning out real, tested recipes — collapsing traffic and setting home cooks up for disaster, especially this Thanksgiving.

Biologists have found that morning light strongly influences our bodies' readiness to wake up. Your experience sounds consistent with that. Shifting daylight from AM to PM in winter would not really help.

Proposal on implementing permanent time zones in the EU — BTUI The proven benefits of clocks being aligned with solar time urge for the implementation of permanent time zones in Europe.

The current version of that proposal is here:

This week I learned that in Italy, DST is "ora legale" and standard time is "ora solare."

State legislators do, and concern about neighboring states usually comes up in the debate. If there's a metro area near the state line, they get an earful from that chamber of commerce.

Before the Uniform Time Act of 1966, ~20 states kept standard time year round. If they hated it, they were free to do something else.

Then seasonal DST became the national policy, and only a few states found the nerve to be different from their neighbors.

The eastern edge of the zone has solar noon at 11:30 EST or 12:30 EDT on average.

Slanted which way? Optimizing winter sunrise/summer sunset would mess up summer sunrise/winter sunset, and vice versa.

The 1974 experiment was year-round DST. @savestandard.bsky.social opposes doing that again and supports year-round standard time, which many states observed successfully until 1966.

The original DST pusher was William Willett, a morning person who wished night people would not "waste" summer mornings. He proposed smaller steps to ease the withdrawal symptoms.

Darkness at 5 PM is due to nature providing less than 10 hours total daylight.

Editorial: Leave clocks alone. Our health depends on it There are some economic reasons for permanent daylight saving time, but the health and safety reasons for permanent standard time overwhelm them.

anyone who bitches about daylight savings this time of year (outside of the adjustment the first week or two or a parent) doesn't have to wake up early bc the only reason i am a functional human at work is because it is light out at 7 am
