GOOD NEWS FOR CHILDREN OF ALL AGES.

The convention, years ago, was that the kids could play outside after school until the streetlights came on.

Under standard time, play time ends early much of the year.  Under all-year-round daylight saving time, play time ends at a reasonable supper time during the winter, and there's plenty of after-supper play time much of the year.

That diagram is from a Steven Taylor post in Outside the Beltway, with this summary.  "Further, the main issue of contention is the morning, as everyone gets a better sunset situation with DST."  The tradeoff is generally one of child welfare, as that extended playtime comes with a lot of school bus pickups (or kids walking to school, where that still happens) in morning darkness.  The end of two changeovers per year, though, means an end to that foolishness about gaining or losing an hour of sleep.  "[T]he change really does require a physical and mental reset twice a year."  Yes, and kids notice that they have to come in long before supper, and dogs probably notice the same thing, even though supper still comes at 5.30.
