How much is sixty jiazi a year? Why didn't you tell me clearly?

This value is calculated according to the China heavenly stems and earthly branches Chronology, which is absolutely reliable.

note:

1. In the ancient calendar of China, A, B, C, D, E, Ji, G, Xin, Man and Ghost were called "ten heavenly stems", while Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You and Hai were called "ten heavenly stems". The two cooperate with each other in a fixed order, forming the discipline of cadres and branches. Judging from the Oracle Bone Inscriptions unearthed in Yin Ruins, heavenly stems and earthly branches was mainly used to record the date, month, year and time in ancient China.

2. Jia uses the time sequence of heavenly stems and earthly branches.
