🌞 The History Behind Daylight Saving Time
The origins of Daylight Saving Time go back more than a century. It was officially established in the United States through the Standard Time Act of 1918, during World War I, to conserve energy by maximizing daylight hours.
Later, the Uniform Time Act of 1966 standardized when DST would begin and end nationwide. The system was further refined under the Energy Policy Act of 2005, which extended DST by several weeks.
| Key Law | Year Passed | Purpose |
|---|---|---|
| Standard Time Act | 1918 | Introduced DST in the U.S. |
| Uniform Time Act | 1966 | Created uniform start and end dates |
| Energy Policy Act | 2005 | Extended DST to save more energy |
In 2025, lawmakers once again debated making DST permanent under the Sunshine Protection Act, though the proposal had not yet passed.
