Day B and Geng Day: Chen Geng;
Third day, Xin day: when it is morning;
Sunday, not Sunday: Chen Jia;
May Day: Chen Bing time;
It is an unchangeable rule that the time of five cycles a day (Jiazi Day, Jiayin Day, Chen Jiari, Wu Jiari, Shen Jiari and Xu Jiari) and one's own day (Ji Chou Day, Ji Mao Day, Ji You Day and Ji Hai Day) must be Chen Wu's time. Other analogies will do. I have given the rules. Check it yourself.
