Blessed Samhain!
The whole planet (specially the celts, the vikings and their descendants) knows that we’re close to Halloween but now, since I’m meeting with my ancestors (historically, I mean) just discovered the purpose of this rare ritual: the end of the harvest, the end of the light half, and the beginning of the dark half. According to Wikipedia:
Samhain ( /ˈsɑːwɪn/, /ˈsaʊ.ɪn/, or /ˈsaʊn/) is a Gaelic harvest festival held on October 31–November 1. It was linked to festivals held around the same time in other Celtic cultures […] and both the Gaelic and the Catholic liturgical festival have influenced the secular customs now connected with Halloween.
