Can the winter solstice be sacrificed in advance?

According to traditional customs, the winter solstice is an important time to worship ancestors. There is no specific time to go to the grave from the winter solstice, so you can sacrifice in advance according to the auspicious day of the ecliptic. Grave-sweeping sacrifices can be carried out from winter to three days before and after. This arrangement can be decided according to the customs and actual situation of individuals or places.
