Calculation method of annual flying stars

The annual flying star is a kind of flying star, which is replaced by heavenly stems and earthly branches every year after beginning of spring.

Example formula:

In the Yuan Dynasty, Jia Zi was white, in the Yuan Dynasty, four green Jia Zi swam, and in the Yuan Dynasty, seven red ones were sent up, so the nine planets went against the year.

In the ancient calendar, 180 years is a week, and 60 years is a jiazi, which is called ternary.

The first 60 years were called Shangyuan, the middle 60 years were called Zhongyuan, and the last 60 years were called Xia Yuan.

Three yuan is divided into nine transports, and each transport is a flying star, which is in charge of good or bad luck for 20 years and 180 years.
