March 12, 2017, is when we “spring” forward for more daylight during DST. Here are the best memes about losing sleep and more when we move our clocks forward an hour at 2 a.m. Daylight saving time, sometimes incorrectly called “daylight savings time,” is a mostly America and European practice. However, it is a much older practice that has roots in ancient history. Learn more about the origins and history of daylight saving time here. Ancient Egyptians were the first people to document having a 24-hour day. They divided the day into two, 10-hour segments. They then added one hour at each end of the 10-hours: one for dawn and one for twilight. Thus, a 24-hour day was born, reports Science ABC. Ancient Egyptians measured the day with devices like shadow clocks. However, the Babylonians were the first to divide an hour into 60 minutes. The division comes from their sexagesimal (counting in 60s) system for mathematics and astronomy. They derived their number system from their predecessors, the Sumerians, who used the sexagesimal as early as 3,500 B.C. Scientific American writes, “Although it is unknown why 60 was chosen, it is notably convenient for expressing fractions, since 60 is the smallest number divisible by the first six counting numbers as well as by 10, 12, 15, 20 and 30.” (Imgur)
