Sexagenary schedules were used so you can count age, days, months, and you will portions away from twenty four hours by using the number of Celestial Stems and you may Terrestrial Branches. Utilization of the 60-day duration is visible throughout the basic astronomical info. In comparison this new 60-year cycle was produced in the 1st century C.E. or 100 years prior to.
