March is an auspicious day to worship the new grave.

In March 2023, there were 20 auspicious days for grave-sweeping, namely:

March 1, March 4, March 5, March 6, March 7, March 8, March 1, March 14, March 15, March 17, March 6555. In my opinion, in some areas, tombs should be cultivated within three years after the completion of new tombs: descendants need wine and food, three sacrifices and five fruits to worship, and the first year of tomb opening should be after the Spring Festival and before Tomb-Sweeping Day. "New graves don't serve the society" refers to new graves, that is, people who died in the previous year or that year. In some areas, people who die within three years of their new death should sweep graves before the spring society. Spring Club Day is the fifth May Day after beginning of spring. Since then, every time before and after Qingming Festival, children and grandchildren have to take fruit tomb paper to sweep the grave.

Solemnly declare: the answer is for reference only, please don't be blindly superstitious.
