In more recent years, the "Spring ahead" shift has been the second Sunday in March, and "Fall back" was the first Sunday in November.

This year, "Spring ahead" was March 12. Sunrise abruptly shifted from just after 6AM to just after 7AM. I'll be feeling "jet lag" for a week or so.

I, and billions of others around the world, beg to differ.

You are displaying your parochialism.

Can you explain BST?

Re DST: there's a yearly debate in the newspapers and elsewhere about quitting this nonsense. Problem is, the EU has to reach consensus for abandoning DST, which proves to be problematic, to say the least.
Interestingly, there was an online questionnaire some years ago, where I believe Germany had the highest turnout. But most of the people voted for permanent DST. I'm really holding my breath that this doesn't go through, should they ever decide to stop fiddling with the clocks twice a year.
People are so flexible today with respect to working hours. If they want more quality time in the evening, they can simply start working earlier. It has exactly the same effect. Granted, some workplaces are not that flexible, but I believe most are.
Claiming that there's more daylight in the evening is just
Besides, I want that hour back that was stolen in March, or I'd be trapped in a lifetime jetlag...

Sorry... I needed that now, this issue is driving me bonkers...

All of my systems use UTC. No matter where they are. It's just easier when doing time-domain analysis.

/Some/ humans expect Mr. Sun to be up when they are. Rarely Universal... 9^)

Can but am reluctant to do so given the prevalence of half-way decent search engines.

OK, but only because I am an old softy ---I have been going soft in the head for some years now.

BST is British Summer Time, often referred to as British Silly Time.

It is amazing how many people around the world think that GMT is the local time in the UK. I have been bitten by that misconception. A group of astronomers based in London organized an on-line meeting which started at "16:00 GMT". A bunch of us, not all British, tuned in as the meeting was about to end. The subsequent embarrassment has led them to announce the starting time in UTC ever since.

I never claimed the Uniform Time Act of 1966 applied anywhere than the USA.

Some US States and Territories don't do Daylight Saving Time. In the Continental US, Arizona does not (although the Navajo Nation does.)

Here in the USA we've never had "Double Summer Time."

The present scheme for switching to and from Standard Time in the US, extending Daylight Time by over a month, was adopted in 2005. One recent year (I believe it was 2020, when the time change was on March 8), the latest sunrise where I live was the first day of DST. This, after sunrise had been getting earlier by the day since early January.

I'd be fine with staying on Standard Time year-round.

The other state that doesn't do savings time is Hawaii - there's no point to savings time if you are in a tropical region, the length of the day doesn't change enough.

Arizona doesn't do savings time because it's too bloody hot during the day in the summer, you need the sun to be down before it's comfortable outdoors.

Personally, I hate savings time, and don't understand the states that want it year-round. We've tried that before, and it was a disaster.

La Palma, and Canarias generally, is sub-tropical and there is no great need for changing civil time.

The reason we do so is entirely political: it keeps us in step with mainland Spain and, therefore, with the rest of Europe.

Even so, we are about 1.2 hours adrift from solar time in winter, 2.2 hours in summer, because we are so far west.
