… In this latest chapter of humanity’s ongoing and continually controversial experimentation with time, Brazil, after nearly a century of begrudgingly changing the clocks every few months, has called off daylight saving time. “Even if it was only an hour, it messed with people’s biological clocks,” President Jair Bolsonaro reasoned when he signed the decision last year. …
Much of the world is increasingly considering whether it should follow suit. In the United States, the rush is on in statehouses and Congress to do away not with daylight saving time but to nix standard time, if anyone can agree on such a thing. “Making Daylight Saving Time permanent is O.K. with me!” President Trump tweeted last March. And on the other side of the Atlantic, the European Parliament voted last year to do away with all of the clock jiggering.
“Let’s end this once and for all,” urges an online petition in the United States that has collected 250,000 signatures. “End the madness.”
But many Brazilians, now months into the change, are here to say: Be careful what you wish for. Brazilians have never been shy about complaining about their country, whether it’s the crime, the social inequality or the corruption. Now, as days begin earlier than anyone can remember, they’ve added a new one to the list. …
“I never knew I liked daylight saving time until it was gone,” added a third.
I think some of the recent complaints about daylight savings time have to do with how Congress fine-tuned the dates of the clocks shifts. When I was young, both Daylight Savings Time and Standard Time were six months long, but now DST is 7 months and 3 weeks long while standard time is 4 months and 1 week long. So the more irritating of the two clock shifts — Spring Ahead when you lose an hour of sleep comes only 4 months and 1 week after Fall Back, so it seems like they are constantly fiddling with the time, so why not just get rid of Standard Time altogether?
But winter mornings with Daylight Savings Time are awful, as Americans discovered in 1974 when we briefly went to year-round DST due to the Energy Crisis. Practically everybody has forgotten that experiment, because only a few of us are sunrise/sunset nerds.
If we really, really needed a single year round time, it would probably make sense to compromise by moving the clocks forward permanently by 30 minutes. That would give us 30 minutes more daylight on summer evenings than Standard Time and 30 minutes less darkness on winter mornings than Savings Time.
But being 30 minutes off from most of the rest of the world would tend to be annoying for everybody.
