What time is C?

C does not belong to any time. Because time is arranged according to the earthly branch. And c is one of the ten days' work. A, B and D all belong to heavenly stems, and there is no fixed representative time. The twelve earthly branches represent time and hour.

In addition, heavenly stems and earthly branches, referred to as Ganzhi for short, originated from the observation of astronomical phenomena in ancient China. In the simplified heavenly stems and earthly branches, "A, B, C, D, E, Ji, G, Xin, Man and Ghost" are called ten heavenly stems, and "Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai" are called twelve earthly branches.
