Here's a look at when the time changes for daylight saving time and who instituted daylight savings in the first place.
Daylight saving time begins on Sunday, March 12, 2023, when the clocks skip ahead an hour at 2 a.m. local time. The clocks will fall back again on Sunday, Nov. 5, 2023 at 2 a.m. local time, when daylight saving time ends for the year. These fall and spring time changes continue a tradition started during World War I.
So when does the time change? Starting in 2007, DST begins in the U.S. on the second Sunday in March, when people move their clocks forward an hour at 2 a.m. local standard time . Daylight saving time then ends on the first Sunday in November, when clocks are moved back an hour at 2 a.m. local daylight time .
After the war, a free-for-all system in which U.S. states and towns were given the choice of whether or not to observe DST led to chaos. And in 1966, to tame such"Wild West" mayhem, Congress enacted the Uniform Time Act.
The nominal reason for daylight saving time has long been to save energy. The time change was first instituted in the U.S. during World War I, and then reinstituted again during WW II, as a part of the war effort. During the Arab oil embargo, when Arab members of the Organization of Petroleum Exporting Countries stopped selling petroleum to the United States, Congress even enacted a trial period of year-round daylight saving time in an attempt to save energy.
Part of the trouble with estimating the effect of daylight saving time on energy consumption is that there are so few changes to the policy, making before-and-after comparisons tricky, Hadley told Live Science. The 2007 extension of daylight saving time allowed for a before-and-after comparison of only a few weeks' time. The changes in Indiana and Australia were geographically limited.
Over the years, state legislatures have considered at least 450 bills to establish year-round daylight savings time, according to the National Conference of State Legislatures . And as of 2022, at least 19 states had introduced legislation to make standard time permanent, doing away with DST all together. However, the U.S. Congress would have to amend the Uniform Time Act to authorize states this allowance, according to The New York Times .
