There is a saying in the northeast that it is forbidden to break ground in leap months, that is, it is not allowed to add graves, but you can go to the graves. There are two explanations for not breaking ground in leap year. First, there is a leap month in the lunar calendar, and it is not allowed to break, change or move the tombs of civil houses within one year. First, there is a leap month in the lunar calendar, which is a leap month. You can't build a tomb, change it or move it in that month.
Funeral geomantic omen emphasizes heavy mourning. What is heavy mourning? The formulas for heavy mourning are "even seven consecutive years, one Geng, two eight and one Xin Dang, etc." That is to say, it is a day of mourning to meet A in the first month, G day of mourning in July, B day of mourning in February and Xin day of mourning in August. /Because the first month was built as Yin, the underground branch was hidden in Jiagan, and it was built as Shen in July, and the underground branch was hidden in Genggan.
Mao was built in February, and the ground branches were hidden in Ganb, and Mao was built in August, and the ground branches were hidden in Xingan. This is the same as the Japanese intervention in the construction of the moon and the earth, and it is also repeated for the sky. Repetition means starting over. In funeral geomantic omen, repetition means killing people. Therefore, it is not appropriate to bury, move graves or break ground in leap years, because interfering with daily work is the same as mourning.
The origin of the leap:
Lunar calendar is a traditional calendar in China. The traditional lunar calendar is based on the lunar calendar and combined with the solar calendar, that is, the combined calendar of yin and yang. The solar calendar is based on the tropical year when the earth revolves around the sun. The lunar calendar determines the date and month according to the change of the moon's profit and loss and the phase of the moon.
The average lunar month is 29.5306 days, and 12 lunar month is 354 days or 355 days, which is about 1 1 day different from the tropical year of the solar calendar (about 365.25 days), and the accumulated time difference in three years will exceed one month. Because of the solar calendar, the lunar calendar is a calendar that takes into account the relationship between the sun, the moon and the earth, and belongs to the yin-yang calendar.
Because the pure lunar calendar does not consider the movement of the earth around the sun, the changes of the four seasons have no fixed time on the lunar calendar and cannot reflect the seasons. Unlike the Gregorian calendar, which is fixed at 365 days or 366 days, the Gregorian calendar sometimes differs from the Gregorian calendar by one month.
In order to coordinate the number of days between the lunar year and the solar year, the lunar calendar adopts the "leap method" to adapt to the total number of days in these two years.
