Most of the North America will follow with the end of daylight saving time one week later, on November 3rd.
The first implementation of daylight saving time or DST was by Port Arthur (Thunder Bay today), in Ontario, Canada, in 1908, but only locally, not nationally. The first nation-wide implementations were by the German and Austro-Hungarian Empires, both starting on 30 April 1916. Since then, many countries have adopted DST at various times, particularly since the 1970s energy crisis.
Proponents of daylight saving time argue that most people prefer a greater increase in daylight hours after the typical nine to five workday. Supporters have also argued that DST decreases energy consumption by reducing the need for lighting and heating, but the actual effect on overall energy use is heavily disputed.
The clock shift is also motivated by practicality, allowing people to wake closer to the sunrise and be active in the evening light.
Daylight saving time is not usually observed near the equator, where sunrise and sunset times do not vary enough to justify it; conversely, it is often not observed in places at high latitudes where a one-hour clock shift would provide little benefit because of the wide variations in sunrise and sunset times. Consequently, only a minority of the world's population uses DST.
