What do you mean the new grave is not a club?

To the new grave, that is, those who died the year before or the year before,

Spring Club Day is the fifth May Day after beginning of spring. In 2023, beginning of spring is on February 4th, beginning of spring is on September 4th, the second is on February 9th, the third is February 19, the fourth is March 1, and the fifth is March 1 1.

I heard people say that social day is beginning of spring before, probably because it is really close to the vernal equinox, and I don't want to do complicated calculations, which is not bad. Social Day is a traditional festival for ancient farmers to worship their landlords. Before the Han Dynasty, there were only spring clubs, and after the Han Dynasty, there were only autumn clubs.

There was no fixed date in ancient times, and the auspicious days of Qin, Han, Wei and Jin were different. Since the Song Dynasty, the fifth day after the vernal equinox and beginning of autumn has been regarded as social day.
