Ask about the demarcation point of the zodiac in the perpetual calendar.

Calculation:

Heavenly stems and earthly branches in order:

Heavenly stems: A, B, C, D, E, Ji, G, Xin, people, ghosts.

Ground branches: Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, Hai.

Tiangan: Nian ÷ 10, regardless of the quotient obtained, see the remainder. If the remainder 3 is positive, count down according to the order of heavenly stems, and the number obtained is the order number of heavenly stems. If the remainder -3 is negative, it is+10, and the obtained number is the heavenly stem number. If the remainder is 3, it is the last digit of the sky, that is 【

Ground branch: year ÷ 12, regardless of the obtained quotient, see the remainder. If the remainder 3 is positive, count down according to the order of ground branches, and the number obtained is the number of ground branches. If the remainder -3 is negative, it is+12, and the obtained number is the ordinal number of the earthly branch. If the remainder is 3, it is the last bit of the earthly branch, that is, [Hai].

Combine the number of heavenly stems with the number of earthly branches, that is, the year of heavenly stems and earthly branches.

For example, the calendar year of 200 1 is a new year, and the algorithm is:

2001÷10 = 200 ...1,1-3=-2, -2+ 10 = 8, and count to 8, a, b, c and d in chronological order.

2001÷12 =166 ... 9, 9- 3=6, and count to 6 in the order of earthly branch, child, ugly, yin, moth, Chen and Si. The sixth place is the third place.

According to the above calculation results, combined with heavenly stems and earthly branches, it can be seen that 200 1 is Xinsinian.

For another example, 1980 is the year of Geng Shen.

1980 ÷10 =198, if the remainder is 0, then 0-3 =-3, -3+ 10 = 7, and count to 7 in the order of heaven and earth, that is, a, b, c, d, e, and so on.

1980 ÷12 =165, if the remainder is 0, then 0-3 =-3, -3+ 12 = 9, and count to 9 in the order of earthly branches, that is, Zi, Ugly, Yin, Mao and Chen. The ninth place is Shen.

According to the above calculation results and heavenly stems and earthly branches, we can know that 1980 is the year of Gengshen.

Another example is: in 2022, the calendar was Ding Younian.

2022 ÷ 10 = 20 1 ...7, and the remainder is 7, then 7-3 = 4 is a goddam.

2022÷ 1 2 =168 ...1,and the remainder is1,then 1-3 =-2,-2+12 =/kloc-.

According to the above calculation results, combined with heavenly stems and earthly branches, we can know that 2022 is the year of Ding You Rooster.
