All Souls' Day is celebrated November 2, and is dedicated to those have died and have not reached heaven. They are either in purgatory or unhappy ghosts.
There are three days that are frequently confused with dealing with the spirits of the departed: Halloween, October 31, which is believed to be when the veil is thinnest between this world, and those of the dead; All Saints is a church-wide holy day of obligation and normally celebrated on November 1, it’s also known as All Hallow’s Day, and it is dedicated to the saints and martyrs of the Church, that is, all those who have attained heaven; and November 2, All Souls' Day, is the one where remembrance is made of those that have died especially family members, but there are special efforts made to appease the ghosts of those who have no family and have been forgotten, because these spirits in their unhappiness can cause a lot of trouble for the living.
