In summer, we have about 15 hours of daylight and 9 hours of night. In winter, we have about 9 hours of daylight, and 15 hours of night. In summer, on standard time,, we get about 3 more hours of daylight in the morning, and 3 more hours of daylight in the evening than we do in winter.

Suppose you use a constant schedule year round, and set your alarm clock to wake you 30 minutes before sunrise in the middle of winter. If you kept that same alarm into summer, you would be sleeping through the first 2.5 hours of daylight.

DST "saves" one of those morning hours, by shifting the clock forward. Relative to standard (winter) time, you add 2 hours of daylight in the morning, and 4 in the evening, instead of 3 and 3. Switching to DST (theoretically) minimizes disruption to our morning schedule.

I think we should focus on the evening instead of the morning. The evenings are where the overwhelming majority of us are free of work, school, and other obligations. Our mornings belong to bosses and teachers; The evenings are our time for home and family, rest and recreation.

If we are going to change times, we should reverse the time change. Instead of "falling back", we should skip forward in November, minimizing disruption to our evenings instead of their mornings. Imagine winter sunsets at 6:30 PM instead of 4:30PM. Imagine the kids being able to play outdoors for two more hours after school than they currently get.

Alternatively, (and preferably) we should just stay on "Summer" time year round.
