Halloween, celebrated on the eve of October 31, originates from ancient Celtic harvest festivals, especially the Gaelic festival Samhain, symbolizing the transition from harvest season to winter - a time associated with death. As the centuries rolled on, Halloween modernized, incorporating practices like trick-or-treating, which descended from medieval practices of 'souling' and 'guising'. People visited homes and received food in exchange for prayers for the dead. Another cherished tradition is carving pumpkins into jack-o'-lanterns, a practice rooted in an Irish myth about 'Stingy Jack'. And then there are the costumes, a significant element of Halloween, initially worn to repel harmful spirits. As Halloween continues to evolve, these traditions remain its heartbeat, making it a truly unique celebration.
