Can leap month break ground and repair graves?

Some people think that graves can't be built, because the lunar calendar will have a leap month every three years or so, so that the lunar calendar and the solar calendar can be relatively coordinated. Leap month is considered as an abnormal month, so it is considered unlucky to repair graves in Tomb-Sweeping Day during the leap month. But in fact, this is just a superstitious concept with no scientific basis.

Leaping month is one of the ways of calendar leap. That is 1 month added in the leap year of the lunar calendar. The lunar calendar is a lunar calendar, which stipulates that a month without gas is a leap month, and the name or ordinal number of the month above is called a "leap month". [5] When ancient astronomers compiled the lunar calendar, in order to make any day in a month contain the meaning of the moon phase, that is, the first day is a moonless night and the fifteenth day is a full moon. Taking the first day as the main basis, taking into account the seasons and seasons, they adopted the method of seven leaps in nineteen years: there are twelve flat years in the nineteenth year of the lunar calendar, and there are twelve months in an average year; There are seven leap years and each leap year has thirteen months. [4] In Asia (especially in China), leap month refers to one month added every two to three years in the lunar calendar. In order to coordinate the contradiction between the tropic year and the lunar year and prevent the lunar year from being out of touch with the tropic year, that is, the four seasons, 1 leap is set every 2~3 years. In ancient times, there was a leap week, and there were seven leaps in nineteen years. By the time of Linde calendar in Tang Dynasty, the fixed leap week was abolished, and the leap was set in the month without season, so it was leap time.
