Contraction of All Hallows' Eve, observed on October 31. The celebration marks the day before the Western Christian feast of All Saints and initiates the season of Allhallowtide, which lasts three days and concludes with All Souls’ Day.

Halloween had its origins in the festival of Samhain among the Celts of ancient Britain and Ireland. On the day corresponding to November 1 on contemporary calendars, the new year was believed to begin. That date was considered the beginning of the winter period, the date on which the herds were returned from pasture and land tenures were renewed.
