Why Do We Celebrate Halloween?

Halloween, which is celebrated annually on October 31st, is a tradition that intertwines ancient beliefs, seasonal events, and cultural change, including Samhain, a Celtic festival where people believed the line between the living and dead was blurred and spirits walked the Earth. To deter unwanted spirits, they lit fires and wore costumes. 

The Christian church also formally adopted All Saints' Day, which was thought to have absorbed Samhain. The night before All Saints' Day became known as All Hallows' Eve, which has since been shortened to Halloween. 

Eventually, traditions of trick or treating, costumes, and jack-o'-lanterns formed, blending cultural folklore with festive fun. Today, Halloween is celebrated globally, marking a night of creativity, community, and playful creepy-fun.

1 Celtic Origins: Samhain

Halloween originates back over 2,000 years ago with the Celtic festival of Samhain, which was celebrated in the territory now known as Ireland, the UK, and northern France.

The Celts marked the end of the harvest and the coming of winter, which meant death or the supernatural. The Celts thought that on the night of October 31st, the dead walked the earth.

They also thought the line between the living and the dead was thin, so they lit bonfires and wore masks to protect themselves from evil spirits.

2 Influence of Christianity

With the spread of Christianity across Europe, the church created the holiday of All Saints Day to honor martyrs and saints on November 1. The night before this holiday (October 31) was called All Hallows' Eve. All Hallows' Eve was eventually shortened to Halloween. This blend of paganism and the church helped to consolidate the date.

Throughout the years, traditions such as trick-or-treating, costumes, and jack-o'-lanterns started to emerge. Modern-day Halloween or 2025, is now an occasion devoted to fun, imagination, and frights. However, it maintains an association with ancient traditions derived from Samhain and All Hallows' Eve.
