Many years ago when I was in college I had a little dark side and I read numerous books on witchcraft and magic. I used to be completely fascinated by it.
Halloween, or Samhain to witches (an Irish/Gaelic term pronounced "sow-wen"), signifies the beginning of the New year.
Samhain is an important sun festival on the Wheel of the Year, which marks the eight important Sabbats, or festivals, that a practicing witch follows. These holidays are based on rituals dating back thousands of years and mark important seasonal dates like the equinoxes and solstices.
Witches typically celebrate Samhain by doing an evaluation of the past year (or turn of the Wheel) and making a list of what worked and what didn't. Then they banish what they no longer want in their life.
A few years in a row I did celebrate the new year on October 31st. Today it makes me smile and brings back so many beautiful memories. I will cherish then for a long time.
Happy New Year to all you witches out there!
