The biologically optimal time moves around. People wake near sunrise. DST keeps sunrise at a more consistent time at the expense of moving sunset around.

People wake near sunrise because DST keeps moving the fucking clock mate.

Ok, then start school at 8AM one month and 9AM the other month, but don't move the clocks.

  If school times are going to shuffle around, then ther parents' schedules will also shuffle around. Then we have to shuffle schedules for a big chunk of economy every 6 months. How can we optimize that process? Oh wait, let's just move the time around. Aha - now everyone is synchronized automatically.

    It's interesting that the answer you came to wasn't "we should align parents' schedules with the biologically optimal time too."

      How well does the biologically optimal time for parents line up with the biologically optimal time for any and all of their kids in school?

        The point I was trying to make is that choosing an optimum should be centered around the education of the world's children. Standard business hours are really a case of "well, we've always done it this way so why should we change," rather than "this the best thing for the everyone involved." I think we are moving towards that somewhat, with companies becoming more flexible with working hours/locations in the past year and a half.

> People wake near sunrise. I found it surprisingly difficult to find data. Not just data for or data against, but any data at all. What little I found organized by month seems to accurately show the percentage of the month typically on vacation (so people sleep later on average in August than September, or they sleep a lot later in Dec than in Oct due to holidays, at least in the north hemisphere). I theorized that regardless of DST people would wake up later from June thru Nov (DST starts in Nov where I live). Unfortunately the graph shows the opposite trend of people tending to wake up on average almost 4 minutes earlier in Oct than in Sept. Or in spring our DST ends in March, so I expected people to wake up earlier in May than in April, but its the other way around by five minutes. I'd theorize if required wake up times strictly followed solar elevation, then something like a graph of car accidents vs time of day would vary greatly by month, but it doesn't seem to in what little data I could find. "Most dangerous time to drive" graphs seem to imply evening rush hour is a little more than twice as dangerous as morning rush hour so that would seem to imply morning wakefullness problems are statistically insignificant. (Edited to note: I'm not insisting you're wrong, but I am insisting I can't find much of any data on the topic, maybe you are right but nobody knows for certain...)
