> People who believe that it should be possible for a society to agree on things just starting an hour earlier (or later) where it makes sense, all without literally touching a single clock.

To be fair, isn’t that essentially what DST systems are? Literally the way that a society arranges to have everything start an hour earlier or later at different times of year is to designate dates where everyone sets their clocks back or forward an hour.

Granted, it doesn’t fulfill your “all without literally touching a single clock” requirement, because a few types of common clocks still require manual adjustment, but the complaints about DST aren’t about the hassle of literally adjusting the clock on your microwave, right? The complaints are about the sudden disruptions to one’s schedule, especially the amount of sleep one gets on two specific nights every year—and your proposal doesn’t solve that problem. And if we instead agreed to change, for instance, the operating hours of every business twice a year, surely the physical changing of signage would be similarly costly.
