Halloween is a holiday celebrated on the night of October 31. The word Halloween comes from All Hallows’ Evening also known as Hallowe’en or All Hallows’ Eve.
Halloween has its origins in the ancient Celtic festival known as Samhain. The Samhain is a celebration of the end of the harvest season where people gather supplies and prepare for winter.
On the Samhain Festival, people would light bonfires and wear ghost costumes on to mimic or appease the roaming ghosts. Because they believe that on Oct 31 the boundaries between the worlds of the living and the dead overlapped that the dead come back to life and cause unfortunate such as sickness or damaged crops.
Over the time, Halloween evolved into a celebration characterized by child-friendly activities such as trick-or-treating, bonfires, costume parties, visiting “haunted houses” and carving jack-o-lanterns.
