What month is the ugly month? Do you mean the lunar calendar or the solar calendar? Is it related to the year? Is the ugly month different in different years?

The Year of Love and Ugliness is a year of the lunar calendar, such as 190 1, 196 1, 2021(once every 60 years).

The happy and ugly month is divided into solar terms, that is, from the slight cold to the day before beginning of spring (this year's happy and ugly month is from the 13th of the twelfth lunar month to the 12th of the first lunar month). Just look up the perpetual calendar.

The ugly month begins in December of the lunar calendar every year, but there will be a difference of two or three days before and after.

The month after Xin Chou Yue is Renyin Yue, from beginning of spring to the day before Jing Zhe.

There are ten heavenly stems, namely, A, B, C, D, E, Ji, G, Xin, Man and Ghost, and twelve earthly branches, namely, Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai. The ancients put them together in the order of Jiazi, Ugly B and Bingyin (that is, the sky turns six times and the earth turns five times, which is just a cycle). There are 60 pairs from Jiazi to Guihai, which are called Jiazi.
