> which extends daylight hours
No, it doesn't. The number of daylight hours is exactly the same no matter what your clocks do.
All DST does is force everyone to change their schedules so that they wake up earlier, go to work earlier, come home earlier, and go to bed earlier. It effectively forces businesses to open an hour earlier and close an hour earlier because of society's expectations.
When you describe it this way, the entire process sounds like something that takes place in a totalitarian state run by a crazy person. Yet here we are as a group claiming it somehow helps farmers (it doesn't, it makes things more challenging for them). The only people who truly benefit from DST are golfers (and golf course owners) who can leave work an hour early and get in a few more rounds.
