The Sumerians were responsible for dividing time the way we do today. First, they determined that the day would begin at sunrise and end only if sunset, where the night would begin that would only end when the sun rose again. After that, observing the skies and their changes throughout the day and night, they developed a complex, but very efficient, division and timing system. They realized that the day could be divided into 24 hours and that each hour could be divided into 60 minutes, so each minute should have 60 seconds.
