How daylight saving time got started

 Interesting Facts - Germany paved the way for daylight saving time in 1916, becoming the first country... as an energy-saving move in the midst of World War I. While many countries followed suit — mostly in North America, Europe, parts of the Middle East, and New Zealand — some of the world’s 195 countries didn’t. In fact, around the globe, it’s now more common to not make clock adjustments, especially in countries close to the equator, which don’t experience major seasonal changes in day length. In total, around 70 countries observe the time shift, though even in the U.S., where daylight saving time has been a standard practice mandated by federal law since 1966, two states don’t participate: Arizona and Hawaii.
