After AD: Heavenly stems: A 4, B 5, C 6, D 7, Wu 8, Ji 9, Geng 0, Xin 1, Ren 2, Gui 3 For example, if the last number in 1894 is 4, it is year A, and so on. ​ Earthly Branches: Zi 4, Chou 5, Yin 6, Mao 7, Chen 8, Si 9, Noon 10, Wei 11, Shen 0, You 1, Xu 2, Hai 3 Conversion: Divide 1894 by 12, what is the remainder, just find it among the earthly branches ​ 2. BC: Heavenly stems: A 7, B 6, C 5, Ding 4, Wu 3, Ji 2, Geng 1, Xin 0, Ren 9, Gui 8 For example, 7 BC is Year A, and so on. ​ Earthly Branches: Zi-9, Chou-8, Yin-7, Mao-6, Chen-5, Si-4, Wu-3, Wei-2, Shen-1, You-0, Xu-11, Hai-10 Conversion: For example, in 221 BC, -221 was divided by 12. What is the remainder? Find the remainder among the earthly branches. ​ The code is as follows: ​ ​ Algorithm of Heavenly Stems and Earthly Branches 2 ​ The code is as follows: "; } ?> ​
