Halloween is celebrated on 31 October every year. Also called "Hallowe'en", "All Hallows' Eve," and "All Saints' Eve," it is celebrated on the eve of All Hallows (or All Saints), a time Christians remember the dead and saints by conducting church services, prayers and fasting. However, the festival is celebrated by people from all walks of life irrespective of religion and region.

According to Halloween History website, Halloween originated in the ancient Celtic festival known as Samhain, which celebrates the end of the harvest season in Gaelic culture. Samhain was a time used by the ancient pagans to take stock of supplies and prepare for winter. The ancient Gaels believed that on 31 October, the boundaries between the worlds of the living and the dead overlapped and the deceased would come back to life and cause havoc such as sickness or damaged crops.

The festival is celebrated with costume parties, making bonfire, trick-or-treating or guising, apple bobbing, making jack-o-lanterns, divination, playing pranks and visiting haunted houses.
