Is going to the grave according to the solar calendar or the lunar calendar?

First of all, it should be noted that the graves in the last years (including multiples of two years, three years and five years) are traditional customs in China and are arranged according to the lunar calendar. As modern China adopted the new calendar, public commemoration and memorial activities also adopted the Gregorian calendar, such as commemorating the centenary of Chairman Mao's birthday and the 0/00th anniversary of the Revolution of 1911/KLOC-0, etc., but folk commemoration activities such as going to the grave were still arranged according to the lunar calendar date.

Second, there is a folk saying that "the dead don't leap in the moon", so the leap month factor must be considered when going to the grave. If the leap month occurs after the death day, there is no need to consider the leap month problem; And if the leap month occurs before the death day, the time to go to the grave must be one month in advance.

Thirdly, there are some details about going to the grave in northern China, such as "going to the grave for nine years" and "not going to the grave twice a month". The landlord can ask the old people nearby.

Finally, I want to say that this is a traditional custom and cannot be discussed by feudal superstition. In addition, in order to arrange as many relatives as possible to participate in the activities, some people may choose a public holiday a few days in advance, but generally do not choose to postpone it. This is also an innovation of civilized sacrifice!
