How to calculate the age corresponding to 60 Jia?

Since the sixty jiazi is composed of twelve earthly branches and ten heavenly stems, each zodiac animal has an average of five jiazi. Also, because of the twelve-year cycle of the zodiac, the difference between the upper and lower parts of each zodiac is twelve, that is, the tolerance is not 12.

For example, the five sons of the Rat Zodiac are: Wuzi 12 years old, Youzi 24 years old, Jiazi 36 years old, Renzi 48 years old and Gengzi 60 years old.

For example, this year is the year of Jihai, and the person born in Jihai is 0 years old. The following year was Xinhai, 12 years old, Guihai was 24 years old, Yihai was 36 years old, Dinghai was 48 years old and Jihai was 60 years old.
