There Is No Arizona
Apparently, Arizona is the only state in the 48 continental United States that doesn’t observe Daylight Savings Time. Hawaii is another state that doesn’t follow the tradition. Additionally, Puerto Rico, a US territory, also doesn’t adhere to Daylight Savings Time. We change our clocks according to the light, which is derived from farming schedules.
Daylight Savings Time actually originated during World War I. The idea was to decrease the use of artificial light to save fuel, hence the turning of clocks ahead by one hour. It started with the German Empire, and soon other countries followed. However, Arizona’s climate is so hot that, should the clocks spring forward, it would stay brightly lit outside until nighttime.
