Daylight Saving Time Ends

Daylight Saving Time Ends History

Daylight Saving Time Ends, commonly known as "fall back," is the annual practice of moving clocks one hour backward in order to allow for more daylight in the evening during the warmer months. This change effectively shifts the hours of daylight to better align with the hours when most people are awake and active, providing additional daylight for work, leisure, and energy conservation. The primary purpose of this time shift is to make better use of daylight and reduce energy consumption, as well as to decrease the number of traffic accidents and crime rates.

The concept of Daylight Saving Time was first proposed by Benjamin Franklin in 1784 but was not widely adopted until World War I when Germany implemented the practice to conserve fuel. Since then, numerous countries have adopted, adjusted, and abandoned the time change based on local needs and preferences. In the United States, Daylight Saving Time was standardized by the Uniform Time Act of 1966, which established the specific dates for the beginning and end of the time change. However, individual states and territories are not required to observe the change, and Arizona and Hawaii currently do not implement Daylight Saving Time.

Daylight Saving Time ends in the United States on the first Sunday in November, marking the return to Standard Time. At this time, clocks are turned back one hour, effectively increasing the number of morning daylight hours while resulting in earlier sunsets in the evening.
