The Irish equivalent to America’s Halloween is Samhain. You are never to go outside at night on Samhain, as it is believed you will hear banchees which will lead to cursing or death. At 11:59 the head of your house will go outside, then at the strike of midnight, he will knock on the door and come in. The day after Samhain is called All Saints Day. They spend the day honoring all saints that have come before them. This is a very important day in the Catholic Church.
