In about 1974, the U.S. Congress mandated that the entire country remain on a daylight savings clock all year long. The oil producing countries (OPEC) were holding back petroleum exports to the U.S. By retaining daylight savings time in the winter, our basic work and school days occurred during daylight hours. Offices didn’t need to turn on lights during the last hour or so of the 9-5 workday. Presumably, using less electricity during daylight savings time would reduce usage of petroleum.
K-12 schools were in session during daylight hours. However, people discovered that children were heading off to school while it was still dark. Young people who had after-school activities were also coming home in the dark. As a safety matter, parents didn’t like the idea that their children were between home and school in the dark. Parents who would not let their children ride bicycles at night found that they were in a position to decide whether the youngsters would take bicycles to and from school.
After one winter, Congress resumed the previous winter clock of standard time. Youngsters, for the most part, were again outside during daylight hours.
To cite examples for the northern tier of states, the sun rises in December, January, and February at about 7 – 7:15 AM. In terms of daylight savings time, the sun rises between 8 and 8:15 AM.
At the same time, in most of the southernmost states, the sun rises in December, January, and February at about 7 AM. In terms of daylight savings time, the sun rises a little before 8 AM except in January when the average is about 8:15 AM.
However, on Florida’s panhandle (in the eastern time zone) the winter sunrise is around 7:30 AM – 8:30 AM daylight time. A legislative discussion in Florida has been to enact daylight savings time all year long. As such, youngsters in Tallahassee, the state capital, would be heading to school in the dark during the winter.
It seems that legislators in Florida do not have the experience of winter 1974 at their fingertips. Some hadn’t yet been born; others wouldn’t remember, of course.
Only Southern California seems to have an advantage over most other populous regions of the country by about fifteen minutes, though.
Those who do not learn from the past are doomed to repeat it.
