Halloween's Origin | ハロウィーンの由来 - What do we celebrate on Halloween?

Halloween (a contraction of All Hallows' Evening), also known as All Hallows' Eve or All Saints' Eve, is a celebration observed in a number of countries on October 31st, the eve of the Western Christian feast of All Hallows' Day. It begins the three-day observance of Allhallowtide, the time in the liturgical year dedicated to remembering the dead, including saints (hallows), martyrs, and all the faithful departed.
