How to calculate the first seven, three seven and five seven after the death of the old man?

Burning Seven is a sacrifice day every seven days from the date of death of the deceased, which is called the first seven days, the last seven days, the third seven days, the fourth seven days, the fifth seven days, the sixth seven days and the last seven days.

"The first seven" means "the deceased goes home to say goodbye to their families on this day!" , but this is also a folk feudal superstition; "The first seven days" is one of the folk funeral customs in China, which means that the "soul" of the "deceased" will return home on this day, and then a "farewell ceremony" will be held to allow him to be reincarnated.

Extended data:

There has always been a folk saying that the seventh day after death is a ghost night, during which the soul of the dead person will return to the house where he lived before. So it's also called the first seven.

Seven days ago, the family members of the deceased will prepare a meal for the soul of the deceased in advance, and then avoid it without affecting the eating of the deceased. If you avoid it, you can choose to sleep or pretend to sleep under the covers. The reason for this is that you are afraid that the soul of the deceased will have an idea after meeting their loved ones. This is not conducive to the reincarnation of the dead. At the same time, in the first seven days, the family of the deceased will burn something similar to the childhood of the deceased.
