Hallowe'en is a time of transformations.
In the ancient Celtic traditions (and the modern Wiccan ones), Samhain is the time at which the Goddess — old, and lonely, and missing her lover — goes to the Summerland to be with him. With her goes light and warmth, fertility, and life. The Samhain Sabbat denotes the end of summer/fall and the beginning of the winter seasons, a time when the last harvest has come in and when the herds are pared down to what the community can feed through the winter, and what will be able to reproduce in the spring.
It is a time of plenty, preceding a known time of famine.
It is also the start of the new year.
