It is fashionable among nerdy people, especially programmers who have to deal with the complicated relationship between different ways people describe time, and the actual flow of time, to not like DST. DST is really good, and really simple though. It's a social agreement to do everything an hour earlier in the summer. People like this pattern. Before clocks and railroads and computers, people generally woke up with the sun, and went to bed shortly after dark. In the winter, this meant that people slept a long time, but that was fine because there wasn't much to do in the winter anyhow, and it was better to conserve energy, since there wasn't much food available.<p>Since we now have artificial light and ample food, we prefer to stay up past sundown and get a consistent 7-8 hours of sleep per night. Still though, people like to wake up after sunrise -- the sunlight is a pleasant and natural alarm clock, and waking up with it is built into our biology.<p>In the modern world, most people have to go to work. Most people prefer to wake up, get ready, and then head to work. If work starts at 9:00 without DST, and you're far enough north, the time between sunrise and 9:00 changes a lot. Without DST, people either have to wake up later in the summer, or find something else to do in the morning before they go to work. Most people would rather go to work earlier and go home earlier while it's still light out.<p>Now, you could say, employers could understand this and have different summer and winter hours. That's true, but there's a coordination problem. Suppose a shop opens at 7 in the summer, but 8 in the winter. Maybe their bread delivery happens at 7:30, so now that has to be changed twice a year. That means that the delivery driver's route needs to change because not every shop changes their hours, or if they do, they don't change them at the same time. DST fixes the coordination problem by just relabelling time, so everyone starts doing everything one hour earlier on the same day across the whole country.
