Anotations

Scope note:

The evening before All Saints’ Day, observed on October 31. It initiates the season of All Saints, which lasts three days and concludes with All Souls' Day. In much of Europe and most of North America, the observance of Halloween is largely nonreligious and has taken on the customs of pre-Christian autumnal festivals, such as the festival of Samhain among the Celts of ancient Britain and Ireland.
