The whole notion of “daylight savings time” needs to go by the wayside.
I second that notion.
"DST" stands for "Daylight Saving Time" but it is better described as "Daylight Shifting Time," since the change in the clock time simply shifts the daylight time from the morning to the evening hours heading toward the summer and then back again as the U.S. heads toward the winter. There is no "saving time"; you don't even earn extra seconds as interest when you get the standard time back.
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).
Nowadays adjusting the clock twice a year is a compromised solution to providing daylight hours to morning commuters and school children during the winter as well as evening daylight hours to families in the evening to enjoy being outdoors more during the summer.
DST is not needed as much 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.
DST becomes meaningless the closer you get to the poles. However, Alaska, with its two time zones, still uses DST, even though parts of the state have daylight all day during some of the summer and no daylight in some of the winter.
If you want to blame something for having to put up with daylight saving time, blame the 23 degrees tilt of the Earth's axis as it orbits the Sun. Of course, without that 23 degrees tilt, life on Earth might not be possible.
