I want to wish everyone both a Happy Halloween and a Blessed Samhain!
On the pre-Christian Celtic calendar, October 31 was Samhain, pronounced Soo-when or Sow-when, and it marked the day when the world of the living and dead where at the closest. It is also the end of year, with November 1 as the start of the next year. This day is one of the most important Gaelic/Celtic/Pagan/Wiccan/Druidic holidays of the year! And please do not worry about the devil–he is not a part of Samhain. There is nothing evil here.
Samhain/Halloween is a day to remember those who have passed and to think of the future.
