What's the date of the first month of the lunar calendar?

The first month of the lunar calendar in China is generally called the first month. The first month, also known as Meng Chun, Duanyue, Jieyue, Liu Yue, Chuyue, jiayue, New Moon and New Year's Eve, is the first month of the year. It is defined as the first month of the China lunar calendar. The first day of the first lunar month is the traditional Spring Festival. We are used to calling January "the first month", because in ancient times, which month was the first month of each year, and each dynasty was different. The first month of Xia Dynasty is January, Shang Dynasty is December and Zhou Dynasty is November. Every time these dynasties revised the order of the equinox, they called the revised January "the first month". In addition, most ancient emperors accepted the sacrifices of civil and military officials in January. In order to show their solemnity, they changed January to "the first month".
