Halloween” is short for “Hallows’ Eve” or “Hallows’ Evening,” which was the evening before All Hallows’ (sanctified or holy) Day or Hallowmas on November 1. In an effort to convert pagans, the Christian church decided that Hallowmas or All Saints’ Day (November 1) and All Souls’ Day (November 2) should assimilate sacred pagan holidays that fell on or around October 31.


Black and orange are typically associated with Halloween. Orange is a symbol of strength and endurance and, along with brown and gold, stands for the harvest and autumn. Black is typically a symbol of death and darkness and acts as a reminder that Halloween once was a festival that marked the boundaries between life and death.
