What is Daylight Saving Time?

Daylight Saving Time (DST) is the practice of setting the clock forward by one hour during the warmer months to extend evening daylight. This means that clocks are moved forward in the spring and set back in the fall. The primary aim is to make better use of daylight and conserve energy.

Key Features of Daylight Saving Time:

• Typically starts in spring and ends in fall.
• Clocks are moved forward one hour in spring (“spring forward”).
• Clocks are reverted back one hour in fall (“fall back”).
• Not universally adopted worldwide; some regions do not observe DST.

History of Daylight Saving Time

The concept of Daylight Saving Time dates back to the early 20th century. It was first proposed by Benjamin Franklin in 1784 as a way to save energy. However, it wasn’t until World War I that DST was officially implemented in several countries, including Germany and the United States, as a means to conserve fuel.

Timeline of Key Events:

• 1916: Germany and Austria-Hungary first implement DST.
• 1918: The United States adopts DST during World War I.
• 1966: The Uniform Time Act standardizes the start and end times of DST in the U.S.
• 2005: The Energy Policy Act extends DST by several weeks.
