Today's Halloween customs are thought to have been influenced by Christian dogma and practices derived from it. Halloween is the evening before the Christian holy days of All Hallows' Day (also known as All Saints' or Hallowmas) on 1 November and All Souls' Day on 2 November, thus giving the holiday on 31 October the full name of All Hallows' Eve (meaning the evening before All Hallows' Day). Since the time of the early Church, major feasts in Christianity (such as Christmas, Easter and Pentecost) had vigils that began the night before, as did the feast of All Hallows'. These three days are collectively called Allhallowtide and are a time for honoring the saints and praying for the recently departed souls who have yet to reach Heaven. Commemorations of all saints and martyrs were held by several churches on various dates, mostly in springtime.
