Why have daylight Savings time?

Daylight saving time, also known as daylight savings time or daylight time, and summer time, is the practice of advancing clocks during warmer months so that darkness falls at a later clock time.

Daylight saving time was believed to conserve energy. However, it didn’t work.

Daylight saving time in the US started as an energy conservation trick during World War I and became a national standard in the 1960s. The idea is that in the summer months, we shift the number of daylight hours we get into the evening.

Daylight saving time has been in place in nearly all of the United States since the 1960s after being first tried in 1918. Year-round daylight savings time was used during World War Two and adopted again in 1973 in a bid to reduce energy use because of an oil embargo and repealed a year later.

The U.S. Senate on Tuesday, March 15, 2022 passed legislation that would make daylight saving time permanent starting in 2023, ending the twice-annual changing of clocks in a move promoted by supporters advocating brighter afternoons and more economic activity.
