There are good sides to DST, such as coming home “earlier” (by the sun clock but not by the social clock) from school or work and therefore having more hours of daylight during the free time after work. These positive effects may go beyond subjective feelings. A study has shown for example that activity increases with longer evening daylight (Goodman et al., 2014) – albeit with small biological effect sizes (≈6% difference in the daily activity between the Standard Time of the year and DST, adjusted for photoperiod). Interestingly these results of the above study were culture-specific: a significant increase was mainly observed in Europe and to some extent in Australia, while no significant effects or even slightly negative effects were seen in the United States and Brazil.

Fucking duh. This is the sticking point for me, and I am disappointed that the article doesn’t mention the effect of latitude here. Very easy for muricans to say “DST is not useful” when these fuckers never get pitch-black night before 6pm or full daylight before 6am ST.

Brussels is on the same latitude as Calgary. ST robs every office worker of one hour of useful daylight. That’s it. That’s the whole argument for permanent DST. Businesses will not change their opening hours, so permanent ST means a net loss of one active hour in the day for every office worker. Permanent DST in Europe means someone working 9-6 would not have to drive home at night for 4 months of the year and could maybe even take the dog for a walk in the evening sun.
