On Sunday, November 7th, NJ residents change the clocks back by 1 hour. Each year we change the clocks ahead one hour in the Spring and one hour back in the Fall. Why do we do this?  In the U.S. the answer to this goes back to the year 1918 during World War I. This act was called the Standard Time Act of 1918. The idea was if people woke up an hour earlier in warmer months, they’d use less electricity during the day. In 1919 however, the act was repealed as farmers had to wait longer to harvest their crops in the morning. Daylight savings time (DST) returned to the U.S. in 1942 during World War 2. The clocks were set ahead an hour to conserve energy for the war effort, which was nicknamed “wartime. ” At the end of the war in 1945, D.S.T. ended once again. After that states were free to implement D.S.T. if they chose to do so. Several states did different things which made it complicated. Finally, in 1966, Congress passed the Uniform Time Act. This established a yearly time change for the U.S. Today, Arizona and Hawaii are the only states that do not observe or practice daylight savings time.
