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 Samhaim or The Feast of the Sun, a 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.
Druids in Britain and Ireland would light bonfires, dance around them and offer sacrifices of animal and crops. The fires were also intended to give warmth to the households and to keep free from evil spirits. Through the ages these practices changed.
