> I don’t know how someone ever could think this is a good idea
Why is that? Whether or not it’s still a good idea, lots of people have thought so in the past. You don’t see the fact that governments have implemented it as evidence that there has been consensus and something legitimate there you might have missed?
I honestly don’t care if daylight saving is abolished, but when I was younger, I used to think like you do that daylight savings was nonsense and should be ditched. But since then I’ve looked at the sunrise charts and realized what happens in the summer without daylight savings, and I changed my mind, I like what happens. Without daylight savings, summer nights are short and summer mornings the sun comes up at 4am and I sleep through some of the usable sunlight. Daylight savings is an attempt to normalize sunrise time. What, exactly, is “evil” about that?
