What do you mean by gangster days?

Mafia day refers to a day that superstitious people think is unlucky and unsuitable for doing things.

Mafia Day is a day in the old yellow calendar. In the past, people thought that in December, construction, fullness, peace, breaking, closing and closing were underworld days, and division, determination, persistence, danger, success and opening were zodiac days. Therefore, in ancient times, there was a saying that auspicious days were ecliptic days and evil days were underworld days.

There are two main ways to calculate the ecliptic and the underworld. One is twelve places supporting twelve gods, and the other is twelve values. The twelve earthly branches and twelve gods are as follows:

Zi Ri Qing Long, Ugly Day, Yin Ri Tian Punishment, Mao Ri Suzaku, Chen Ri Jingui, Si Ri Tiande, Wu Ri Bai Hu, Wei Tang, Shen Ri Tian Prison, You Ri Xuanwu, Rising Sun Siming, Gou Chen. Those who meet the requirements of Qinglong, Tang Ming, Jingui, Tiande, Yutang and Siming Six Gods are all ecliptic days. On the contrary, it's gangster days.
