Boston mean solar time is 16 minutes ahead of EST or 44 minutes behind EDT. DST is not closer anywhere in the US.

The Eastern/Atlantic zone boundary is already in the right place, near 67.5Β°W.

The sun does not set before 3:30pm standard time anywhere in the contiguous 48 states. It would rise after 9:00am daylight time in some places.

That's an objection to winter.

The Oregon Senate this year passed a bill to observe standard time as Arizona does, but the House ignored it.

I think it's a lot. Its orbital period around the Sun changed from 505 days to 752 days.

Whose fool idea was it to push the end of daylight saving time back to November?? It’s Oct 1 and I already have to get up in the dark and I hate it. Make standard time permanent already!!!

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

Good question. Here's one of a few studies on that.

The study is by researchers at Stanford, published in PNAS.

Winter morning safety is a good reason to keep using standard time at that time of year. It would be OK in summer too.

Winter mornings are naturally a little dark. Extending DST would make them artificially extra dark. The time should be continuous and *neutral*.

Brazil, Iran, and most of Mexico have flipped from blue to orange since that map was made.

The Uniform Time Act of 1966 established the first national DST schedule in peacetime.

North Dakota didn't observe it in peacetime until 1967.

The builder who changed how the world keeps time Britain introduced daylight saving time 100 years ago – and was quickly followed by countries worldwide. Love it or hate it, there’s a stubborn British campaigner you can thank.

DST was a morning person's scheme to make night people stop "wasting" summer mornings. Standard time lets us night people be ourselves.

Eastern Maine could go either way; the rest of New England should remain in the Eastern zone. Some US time zones extend too far west, but none extends too far east.

New England is not in the wrong zone. The Eastern/Atlantic boundary is already in the right place, near 67.5Β°W.

Also if SAD is treated with bright light in the morning, then it does not make sense to darken winter mornings.

25.09.2025 19:38 β€” πŸ‘ 2    πŸ” 0    πŸ’¬ 0    πŸ“Œ 0

No. EST is only 16 minutes behind Boston mean solar time; AST is 44 minutes ahead. The Eastern/Atlantic zone boundary is where it belongs, near 67.5Β°W.

1974 showed that later sunrises make winter commutes more hazardous.

Good news: at your location, standard time is not even dark at 5:14pm.

Tumblr post from every-lemon 
Sep 8

so my spouse is part of a weirdly intense but mostly benign men's workout group that meets at like, 5:30am outside every day, even in winter. they do a lot of burpees and lugging cinder blocks up hills and stuff.
they take turns leading the workouts and tomorrow is his turn. I asked what he was planning. he handed me a sheet of William Carlos William poems from a large stack he'd printed.
I said "what" and he explained, helpfully, "it's a William Carlos William themed workout." I asked what inspired it and he said "l've been planning this for months."

it was a smash hit.
a dozen guys showed up (more than usual). spouse brought a red wheelbarrow and they took turns bringing cinder blocks up the hill with it. then they broke up in teams and did a relay with an "icebox" (cooler filled with 40lbs of ice). at the end he opened the cooler to reveal it was full of beach plum lacroix and all the guys cheered. they drank sparkling water as he read 'approach of winter' out loud.
he was home by 6:30am.

I hope not. When winter makes the daylight short, we need half of it in the AM.

5:30 sunrises aren't bad when nature provides 14 hours of daylight. 12-month DST would come with 2 months of 8:15 or later sunrises.
