Dry days and dry things:
1(A)； 2(b)； 3(c)； Article 4 (d); Article 5 (e); 6 (self); Article 7 (g); 8 (symplectic); 9 (nonyl); 10 (deck).
Grounding branch:
Press1(sub); 2 (ugly); 3 (yin); Article 4 (d); 5 (Chen); 6 (4); 7 (noon); 8 (no); 9 (Shen); 10 (unitary); 1 1 (?); 12 (sea).
Calculate sky dryness:
Any year after A.D.: A.D. -3= the number of digits at the end of the year, negative number plus 10.
Any year BC: year-end digits +8= year-end.
(The formula reveals: Because AD 3 is the year of Guihai, and the heavenly stems are the cycle of 10. In AD 4, the heavenly stems were a, 4-3= 1. Because there is no year 0, the heavenly stems in BC are the last digit-3+1,and then+10 becomes a positive number).
Computational Earth Branch:
Any year after A.D.: (A.D. year -3)÷ 12, the remainder 0- 1 1 is the annual branch, and the negative number is added to 12, and 0 is regarded as 12.
Any year in BC: (AD year -2 years) ÷ 12, and the remainder-1-0 is the annual branch. Add 12 to make it a positive number, and 0 is regarded as 12.
