It will not happen. The science is overwhelming that having one timezone all year long is worse for people, and switching the clock back and forth twice a years is a minor nuisance at most.

The EU's "Ban DST" is the same populist bullshit as Trumps "inject Windex to cure COVID". Based on nothing and ignorant at best.

And the cherry on top is, if you ask the EU if they want to receive a no strings attached gift of €10.000.000.000.000 or €11.000.000.000.000, it would still take them 20 years to decide. No way they will ever reach consensus on DST.

If the science is overwhelming, do you have a source? If not, what are the downsides to having the same timezone all year?

[Some links that I've posted the last few times DST has come up:]

The folks who study this:

* https://en.wikipedia.org/wiki/Chronobiology

Seem to have come to a consensus that if we're going to get rid of DST, then health-wise it is best to have Standard Time year-round:

> As an international organization of scientists dedicated to studying circadian and other biological rhythms, the Society for Research on Biological Rhythms (SRBR) engaged experts in the field to write a Position Paper on the consequences of choosing to live on DST or Standard Time (ST). The authors take the position that, based on comparisons of large populations living in DST or ST or on western versus eastern edges of time zones, the advantages of permanent ST outweigh switching to DST annually or permanently.

For a longer-read, referencing quite a bit of academic literature, but a conclusionary snippet:

> In summary, the scientific literature strongly argues against the switching between DST and Standard Time and even more so against adopting DST permanently. The latter would exaggerate all the effects described above /beyond/ the simple extension of DST from approximately 8 months/year to 12 months/year (depending on country) since /body clocks/ are generally even later during winter than during the long photoperiods of summer (with DST) (Kantermann et al., 2007; Hadlow et al., 2014, 2018; Hashizaki et al., 2018). Perennial DST increases SJL prevalence even more, as described above.

The sun rises in Singapore between 0655 and 0715 depending on the time of the year. How would changing the clock help at all?

[throw0101a]

It wouldn't, as it gets ~12 hours at both solstices:

DST is mostly for countries closer to the poles. See my other comment:

Never heard about windex. Now I know.

Well the majority of people, countries, and square-kilometres of land doesn't have daylight saving so you'll have to do better than that.

At some latitudes with some social norms (regarding things like school start times) DST is beneficial. In others it's not. There are no absolutes here.
