The History of Daylight Saving Time

During the chaos of World War I, an idea emerged to conserve energy by changing the time. The plan involved adjusting clocks to make optimal use of daylight, a strategy born out of the need to save resources. Little did the world know that this wartime measure would evolve into a widely debated subject, sparking discussions among people and governments across the globe.

Daylight Saving Time (DST) still exists more than 100 years later, but why? Join us as we uncover the history behind DST.

The European Onset: Germany and Austria Lead the Way

DST kicked off in Germany and Austria in 1916. By advancing the clock's hands by an hour, these nations aimed to conserve fuel for electric power production. Soon, the concept spread across Europe, reaching countries like Belgium, France, and Britain.

Slow Adoption in the United States

In the United States, DST faced a slower adoption. It wasn't until 1918 that the U.S. officially embraced it with the enactment of the "An Act to preserve daylight and provide standard time for the United States."

This legislation established both standard time zones and the start of summer DST on March 31, 1918. Although initially observed for seven months in 1918 and 1919, the unpopularity of the practice led to its repeal in 1919.

World War II: Wartime Resurgence

President Roosevelt reintroduced year-round DST during World War II, termed "War Time," from 1942 to 1945. After the war, from 1945 to 1966, the absence of federal legislation resulted in varying DST practices across states. This led to a lot of confusion for industries like broadcasting and transportation.

In the wake of this confusion, The Committee for Time Uniformity aimed to standardize DST to support these various business interests. Their efforts revealed the absurdity of time changes along a 35-mile highway stretch from West Virginia to Ohio where travelers endured seven time changes.

The Quest for Uniformity

This ignited public support for uniformity, and in response, the Uniform Time Act of 1966 was enacted, establishing DST to begin on the last Sunday of April and end on the last Sunday of October. States had the option to exempt themselves by passing state laws.

Legislative Shifts: From Nixon to Today

In 1974, President Nixon signed the Emergency Daylight Saving Time Energy Conservation Act. This marked a shift to year-round DST from January 6, 1974, to October 27, 1974. Further changes occurred in 1986, pushing the start of DST to the first Sunday in April. President Richard Nixon signed the Emergency Daylight Saving Time Energy Conservation Act, marking a shift to year-round DST in 1974.

Fast forward to the Energy Policy Act of 2005, which extended DST from 2007 onwards, though Congress retained the right to revert the law should it prove unpopular or ineffective. Presently, DST commences at 2 a.m. on the second Sunday of March and concludes at 2 a.m. on the first Sunday of November.

Over time, DST has evolved to suit energy conservation and societal needs better. Today, when you adjust your clock during spring and fall, you're participating in a time-honored tradition that has weathered wars, public opinions, and legislative amendments.
