Samhain is a Gaelic festival celebrated from sundown on October 31st to sundown on November 1st. It marks the end of the harvest and the beginning of the "darker half" or Celtic New Year.
This transition signifies the cycle of life, death, and rebirth, which was central to Celtic beliefs. All of nature seems to return to the earth, making space for higher consciousness to occur. The Veil between the physical world and the spiritual (or "other") world is considered to be at its thinnest during this time, allowing spirits to easily cross between realms and enter our world.
The ancient Celts would traditionally make offerings of food, drink, and prayers to honor ancestors and appease the spirits of the other realms. This was done to seek their protection and blessings for the coming year and to benefit their harvest and livestock for the following season.
