Daylight Saving Time

Daylight Saving Time
- history -

​​Daylight saving time (or "DST") in its modern form was devised independently by a New Zealand entomologist in 1895 and an English outdoorsman in 1905, both in an attempt to maximize use of daylight hours. The system wasn't implemented on any nationwide scale until 1916, as an effort to save coal by the German Empire in World War I. It was soon after adopted by the United Kingdom, most of Europe, Russia, and the United States.

From 1942 to 1945, the United States adopted a year-round DST ("War Time") to conserve energy during World War II.

Official daylight saving time was relaxed or abandoned by many countries following the war. It was eventually reestablished as a result of massive oil shortages during the 1970s.
