North America isn't alone in the world moving it's time forward in the spring and back in the fall. Across the globe, 79 nations use “Daylight Time” in at least part of their country. The Falkland Islands stay on “Daylight Time” throughout the year. Most countries on Earth, 159 at this time, remain in “Standard Time” all year.
For those countries which use “Daylight Time,” the date on which “Daylight Time” starts and ends varies from country to country, set by government regulation or law. It also varies according to which hemisphere each country is located, north or south.
