Those who want to stick with standard time say it benefits our health, as it is better to have more light in the morning, paving the way for improved sleep cycles on darker evenings. They say DST can be disorienting to sleep schedules.
But others want to make DST permanent instead, arguing that brighter evenings, especially for those commuting from work or school, would reduce crime, conserve energy and even save lives in terms of reduced road accidents.
Both sides say their preferred option would be better for the economy.
Trump’s plan is not the first attempt to alter the biannual practice of changing clocks seasonally in the US.
Making daylight saving time permanent was the aim of a 2022 bill that passed the Democratic-controlled Senate.
But the Sunshine Protection Act, which was introduced by Republican Senator Marco Rubio, never made it to President Joe Biden’s desk.
Rubio, who has since been picked by Trump for the role of secretary of state under his incoming administration, said at the time that studies had shown a permanent DST could benefit the economy.
The US first began changing its clocks seasonally in 1918 during World War One in an effort to conserve fuel. It was unpopular with farmers, and was repealed after the war.
But DST returned again during World War Two, and was made permanent in 1966, though states could opt out.
Hawaii and most of Arizona currently do not follow time changes under DST.
Research by Joan Costa-i-Font, a professor at the London School of Economics, found that DST has had “detrimental effects on sleep and physical health, and on feelings of fatigue, stress, time stress and mental health”.
Prof Costa-i-Font’s study found that, in monetary terms, an end to DST would lead to an increase in economic output of €754 ($792; £627) per person per year, external.
Countries that have ended the practice include Mexico in 2022, though DST is still maintained in regions near the US border for economic and logistical reasons. Jordan also ended the practice that year.
Others, like Turkey and Russia, have implemented a permanent DST instead in the past decade.
In a Monmouth University Poll, researchers found that about two-thirds of people, external in the US want make DST permanent.
