What is the twelfth lunar month, such as twelfth lunar month 18, and what day is it today?

The twelfth lunar month refers to the December of the lunar calendar. Why is it called "La" at the end of the year has three meanings: First, "La" means the alternation of old and new (recorded in Sui Shu etiquette); The second is "wax hunters hunt together", which means that hunting in the wild can make animals sacrifice their ancestors and gods. "wax" comes from "meat", which means meat for "winter sacrifice"; Thirdly, it is said that "those who wax the wax will drive away the epidemic and welcome the spring", and Laba Festival is also called "Buddhist Daoism Festival" and "Daoism Society". In fact, it can be said that the eighth day of December is the origin of Laba Festival. According to legend, Sakyamuni, the founder of Buddhism, practiced in the mountains and sat quietly for six years. He was so hungry that he wanted to give up the pain. He happened to meet a shepherdess and gave him chyle. After eating, he sat cross-legged under the bodhi tree, became a Buddha in early December, and held a "Buddhist Festival" to commemorate it. Believers in China are very devout, so they merged with "La Ri" to form the "Laba Festival" and held a grand ceremony. Laba Festival is the most important festival in December of the lunar calendar, which is the eighth day of December. It was called "Laba Festival" in ancient times, commonly known as "Laba Festival". Since the pre-Qin period, Laba Festival has been used to worship ancestors and gods and pray for good harvest and good luck. In addition to the activities of offering sacrifices to ancestors and worshipping gods, people also have to chase the epidemic on Laba Festival. This activity originated from Nuo in ancient times (the ritual of exorcising ghosts and avoiding epidemics in ancient times). One of the prehistoric medical methods was to exorcise ghosts and treat diseases. As a witchcraft activity, Xinhua and other places in Hunan still retain the custom of beating drums to drive away epidemics in the twelfth lunar month. It is said that the enlightenment day of Sakyamuni, the founder of Buddhism, is also on the eighth day of December, so Laba is also a Buddhist festival, also known as the "Buddhist Enlightenment Festival".
