A brief study on history and evolution of time

Abstract

Time is a phenomenon of periodic changes in our Earth, solar system, and universe. In our Earth, a day has 24 h; 1 h has 60 min and 1 min has 60 s. These all are well known things. One systematic arrangement of time in history is based upon base 60 or Sexagesimal system. If time of Earth is based on the angle of inclination 60° of the plane for solar system with the plane for Milky Way, then the resultant should be based on base number 60 for formation of a calendar of the years. The astrophysical science and mathematical calculations led to the development of time concept year by year with predictions of all events. Those calculations are done with the help of base 60 number system. More specifically, 60 years is the number of years required for Saturn and Jupiter to regain same positions in the solar plane. The cultural festivals and agricultural operations are also based on base 60 system. At finally, human biological clocks subject to the facts are considered.
