This biannual time adjustment, while widely practiced across the United States, does have some exceptions. Most notably, most of Arizona and all of Hawaii do not observe Daylight Saving Time. Neither do US territories, such as, Puerto Rico, Guam, American Samoa, and the U.S. Virgin Islands.
Efforts to establish year-round Daylight-Saving Time have gained traction in recent years, with several states considering or passing legislation advocating for permanent Daylight-Saving Time.
However, federal authorization is required to implement these type changes. Congress would have to take action to amend existing regulations.
Origins
The origins of modern Daylight-Saving Time can be traced back to World War I, with the German Empire implementing the concept to conserve fuel during wartime. The United States adopted Daylight Saving Time in 1918 as a wartime measure, reintroducing it during World War II to aid in energy conservation efforts.
While opinions on Daylight Saving Time vary, with some advocating for its permanence and others preferring standard time year-round, the practice remains a fixture of the modern-day calendar.
