With autumn just around the corner, the United States will bid farewell to Daylight Saving Time (DST) on November 3, 2024. At 2:00 a.m. local time, clocks will be turned back one hour.
On November 3rd at 2:00 AM local time, most of the US will “fall back” an hour. This means clocks will shift to 1:00 AM, giving us an extra hour of sleep and earlier sunrises.
Daylight Saving Time (DST) was introduced to make better use of daylight during the longer days of summer. In the United States, DST starts on the second Sunday in March and ends on the first Sunday in November. The idea first began during World War I and was used again in World War II to save energy. Since then, it has continued to be followed in many areas of the country.
At 2:00 a.m. on November 3, people should remember to adjust any clocks that don’t automatically update, like wall clocks, microwaves, and traditional alarm clocks. While most digital devices, such as smartphones, usually reset on their own, analog clocks will need to be adjusted manually.
States That Do Not Observe Daylight Saving Time
It’s important to understand that not every state in the U.S. follows Daylight Saving Time. Some states have chosen not to participate in this practice, meaning they don’t adjust their clocks forward in the spring or backward in the fall. For example, Hawaii and most of Arizona do not observe Daylight Saving Time. Hawaii opts out because its location near the equator results in fairly consistent daylight hours throughout the year, so changing the clocks doesn’t offer much benefit.
Arizona, on the other hand, has chosen not to observe Daylight Saving Time mainly due to its hot desert climate. By staying on a consistent schedule, residents avoid having longer daylight hours during the extremely hot summer evenings, which helps keep their homes cooler and reduces energy use. This decision allows people in these states to maintain a stable routine without adjusting their clocks twice a year.
