Chronology of Huangdi

Chronology of the Yellow Emperor: Calculated according to the chronology of the Yellow Emperor, heavenly stems and earthly branches and the lineage of the emperor. The time when the Yellow Emperor ascended the throne to create calendars was the first year of China calendar, and Huaxia nationality was one of the earliest nationalities to create calendars.

Because the number of days in the Gregorian calendar is different from that in the Gregorian calendar, the summer calendar of the Yellow Emperor 1 year is 1 13 in October, corresponding to 1 in 2697 BC. Therefore, the first year of Huangdi should be regarded as 2697 BC, which is used to calculate the corresponding trunk and branch of Huangdi calendar on New Year's Day, and then extrapolated to the trunk and branch after 2698. Because when calculating heavenly stems and earthly branches on New Year's Day, 2697 BC is regarded as the era of the first year of the Yellow Emperor, which corresponds to the main branch of the previous year. What is the number at the end of the Yellow Emperor's calendar, that is, the number of heavenly stems. When the calendar year of the Yellow Emperor is divided by 12, what is the remainder? It is the number of earthly branches.
