twenty-four hours a day
The modern 24-hour day came from the 1884 International Conference, which divided the world into 24 time zones. It stipulated that every 15° of longitude on Earth was a time zone (that is, the longitude that the sun traveled in an hour), so there were 24 hours in a day. From the perspective of the Earth's movement, it took 23 hours, 56 minutes, and 4 seconds for the Earth to rotate once. In addition, the revolution was about 0.986 degrees, which was equivalent to 3 minutes and 56 seconds. The total rotation and revolution took 24 hours, which was 24 hours a day. However, the length of a day on Earth was not always fixed. When the moon first formed about 4.5 billion years ago, a day on Earth was less than 10 hours. As the tidal force of the moon slowed down the Earth's rotation, the day gradually became longer. Between 2.2 billion years ago and 600 million years ago, due to several tidal forces canceling each other out, the Earth rotated at the same speed for more than a billion years, keeping the length of a day constant at about 19.5 hours. Today, the length of a day was still slowly increasing. From a precise measurement point of view, if it was defined according to the oscillation of the caesium-13 atom, the true length of a day was 24 hours, 56 minutes, and 24 seconds. In addition, different ancient civilizations had different ways of measuring time. For example, in ancient China, the 12-hour Heavenly Stems and Earthly Branches calendar was used to divide a day. In ancient Egypt, the day was originally 10 hours, but later it was changed to 12 hours by the 12-hour system.
