What is lucky on stir up Sunday?

Stir Up Sunday, observed on the last Sunday before Advent, is traditionally considered a time to prepare for Christmas by making Christmas pudding. The day is thought to be "lucky" because families gather to stir the pudding mixture together, often making a wish as they do so. Each member of the family takes a turn stirring the pudding while reflecting on their hopes for the coming year. This festive ritual is meant to bring good fortune and happiness to the household.
