It was established during World War I as “a way of conserving the fuel needed for the war industries and extending the working day”, according to the Library of Congress. Explained in online post.

But it was only temporary. Almost a year later, on August 20, 1919, as the war ended, the law was repealed.

“However, clauses of the 1918 law, which established standard time zones for the country, remained in effect,” the library said. “In 1921, Congress re-adjusted the western boundary of the Standard Central Time Zone, moving parts of Texas and Oklahoma to the region.”

The topic of daylight saving reappeared during World War II. On January 20, 1942, Congress re-established Daylight Saving Time.

More than two decades later, in 1966, President Lyndon B. Johnson signed the Uniform Time Act into law, declaring daylight saving time as US policy and requiring uniform start and end times within standard time zones. was established.

What are the rules?

Daylight Saving Time and Time Zone are regulated by the US Department of Transportation (DOT) Under the Uniform Time Act, daylight saving begins at 2 a.m. on the second Sunday of March every year

“If a state chooses to observe daylight saving time, it must begin and end on federally mandated dates,” the DOT states.

a bill called the “Sunshine Protection Act”, The move, which allows Florida to be on daylight saving time year-round, was passed in March in the State House and Senate. Gov. Rick Scott then signed the bill into law. However, Congress still Need to amend existing federal law to allow change.

If approved by the federal government, it would effectively move Florida residents one time zone east, aligning cities from Jacksonville to Miami with Nova Scotia instead of New York and Washington, DC.

How does it matter?

There are a number of reasons why officials believe daylight saving time is beneficial.

However, some believe that this procedure is a “trouble”.

Proponents of eliminating daylight saving time argue that it is generally unnecessary, disturbs sleep patterns and has recently become even more complicated. In 1986, Congress extended daylight savings to a period of six to seven months, and increased it again in 2005 to eight months—mid-March to mid-November.

“Congress actually gave us a wise agreement in 1966 with a standard time of six months, but because of the lobby from daylight we now move in the middle of winter,” Michael Downing, “Spring Forward: The The author of “Annual Madness Daylight Savings,” told Granthshala News in 2015.

Disagreements about daylight saving are nothing new. In 1965, before the Uniform Act was passed, 71 major cities in the US with populations of more than 100,000 were using daylight savings, while another 59 were not.

“People don’t like the hassle of adjusting their clocks twice a year,” Downing said.
