Spirit of Holloween

Halloween again is celebrated on the 31 st of October, on the eve of Winter in the northern hemisphere. Yet, at this time it’s the eve of Summer down here in Oz!
According to scholars, Halloween was originally a festival of the dead with pagan roots, along with games traditionally played as a form of divination.
It Celebrates the line between Autumn and Winter, life and death, and superstition.
At the ancient Celtic festival people would light bonfires and wear costumes to ward off roaming ghosts.
Nowadays, typical festive Halloween activities just include trick-or-treating, carving pumpkins, lighting bonfires, visiting haunted houses, playing pranks, telling scary stories, watching horror films, etc.
If we were to acknowledge the true spirit of Halloween, why not celebrate it at the end of our Autumn in April?
