In ancient China, there were 12 hours a day. When is the beginning of a new day?

In ancient China, a new day began at midnight.

In the traditional culture of China, one day and night is divided into twelve hours, each hour is equivalent to the present two hours, and the twelve hours are named after twelve earthly branches, namely, Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai;

Each hour is divided into three parts, namely initial time, timing time and last time;

Every morning 1 1 till midnight 1, and so on.

It can be seen that the traditional dividing line of a new day in China is eleven o'clock (midnight) instead of twelve o'clock (zero point) used in the current Gregorian calendar.
