Halloween, the time of pumpkins, candies, ghosts, witches and much more, is annually celebrated on 31 October. That's the night before All Saints Day. Its origins date back thousands of years to the Celtic festival of Samhain or The Feast of the Sun, most significant holiday of the Celtic year. This day marked the end of summer but also the season of darkness as well as the beginning of the New Year on 1 November. Children love the custom of dressing-up in fancy costumes and going from door-to-door yelling 'Trick-or-Treat?'. Adults instead join spooky parties which are nearly held all over the cities on that special evening. A spooky decoration, games and themed food are nuts and bolts for a Halloween party your friends won't soon forget.
