Twice a year we change our clocks for Daylight Savings Time and Standard Time. Is it time to stop?

Congress is weighing a permanent daylight saving time.

[University of Washington law professor Steve] Calandrillo argued that the nation should permanently adopt daylight saving time to capitalize on as much light as possible in the early evening,

while [Beth] Malow, [director of the Vanderbilt Sleep Division] argued for a permanent shift to standard time, saying that moving the clocks earlier throws off the body’s natural responses to light." She "argued for a permanent shift to standard time, saying that moving the clocks earlier throws off the body’s natural responses to light."

"Daylight saving time “is like living in the wrong time zone for almost eight months out of the year,” Malow testified, citing research into circadian rhythms and release of hormones such as cortisol."

The U.S. Senate on Tuesday passed legislation that would make daylight saving time permanent starting in 2023.

"The National Association of Convenience Stores opposes the change, telling Congress this month "we should not have kids going to school in the dark.""

Congress had voted on December 14, 1973, to put the US on daylight saving time for two years. "President Nixon signed the bill the next day. The US had gone to permanent daylight saving time before, during World War II. Then, too, the measure was enacted to save fuel. "

The 1973 experiment lasted 9 months.
