I thought the main reason for keeping DST is to ensure it is light out when the kiddies are waiting for a school bus.
At 40 deg latitude, approximately the middle of the continental U.S., the width of each time zone is approximately 800 miles (the width is a little more for southern latitudes and a little less for northern latitudes). Areas along the western edge of their time zone will see more daylight later into the evening during DST, and areas along the eastern edge of their time zone will see daylight sooner in the morning during standard time.
Nowadays adjusting the clock twice a year is a compromised solution to providing daylight hours to morning commuters and school children as well as evening daylight hours to workers going home in the evening, and enjoying being outdoors more in the summer.
DST is not as needed the closer one gets to the equator (Hawaii, most of Arizona, Puerto Rico, the US Virgin Islands, Northern Mariana Islands, Guam, and American Samoa do not use DST), and becomes meaningless the closer you get to the poles. Alaska, with its two time zones, still uses DST, even though parts of the state have daylight all day in some of the summer and no daylight in some of the winter.
If you want to cast blame, it's because of the 23 deg tilt of the Earth's axis as it orbits the Sun. Of course, without that 23 deg tilt, life on Earth might not be possible.
I’m for DST all year around. Pretending to save daylight serves no purpose.
We tried this once before and people were complaining that their children were waiting on the bus when it was still dark outside, posing a danger to the children.
What is wrong with the natural time of the earth as measured by when the sun is as approximately straight over head at your location, making the midpoint of the earth’s rotation, or as we generally call it, noon. And all other hours fall ahead of or behind noon. It is economic myth that any benefits of “day light savings time” are not offset on the other end - what “daylight” is added early in the day is taken away later in the day.
According to insurance statistics heart attacks, strokes and accidents spike for a week or so after each time change.
I kind of like the ancient way of time keeping. Day and night were divided into 12 equal parts based on sunrise and sunset. The length of hours vary every day and night.
The Senate passed the Sunshine Protection Act but not the House therefore things continue the way they have been.
