Samhain or Halloween?

Samhain or Halloween? Today is the festival of Samhain as well as one of our favorite Holidays of Halloween.
Samhain is the traditional harvest festival of the Wiccan religion that is celebrated on October 31 to celebrate the harvest and welcome the start winter. Halloween also traditionally falls on the 31st and is the eve of All Hallows Day on November 1 which is also referred to as All Saints Day. Some say that Halloween evolved from Samhain as a form of cultural appropriation in the same way that the pagan festival of Yule was adopted as Christmas. I prefer to not think of it as appropriation but instead as evolution.
