What is Daylight Saving Time?
The practice of advancing clocks by one hour between March and November, which extends evening daylight, allows people to make the most of natural daylight, as per the outlet. However, in November, after Americans “fall back” or return to standard time, more daylight is added to the mornings, according to USA Today. This year, DST ends on November 2, at 2 am local time.
Daylight Saving Time reduces the reliance on artificial lighting in the evening, which subsequently decreases energy consumption. Extended daylight saving time, signed by George W. Bush in 2005, saved about 0.5 per cent in total electricity use per day, according to a report by the Department of Energy, reports The New York Times.
The US Energy Policy Act has carefully laid out rules to standardize the implementation of Daylight Saving Time. However, it is not mandatory for all US states to follow them. For example, Hawaii and Arizona do not observe daylight saving time. At least 66 nations have practiced DST since its introduction, as per HowStuffWorks. But some countries have stopped following it for several reasons.

After Germany adopted DST in 1916 during the First World War for energy conservation purposes, the practice gained popularity worldwide.
The US observed year-round DST in 1974 and 1975 in response to the Arab oil embargo. Finally, 43rd President George Bush extended DST from the second Sunday in March to the first Sunday in November in 2005, as per the outlet.
