Calan Gaeaf, celebrations start at sunset ofOctober 31. (Wales)

A traditional Welsh Celtic festival marking the beginning of winter, celebrated from sunset on October 31 with folklore, bonfires, and divination rituals.
Calan Gaeaf, meaning the first day of winter in Welsh, originates from ancient Celtic customs in Wales. Starting at sunset on October 31, communities light bonfires and hearth fires to ward off evil spirits and celebrate the harvest’s end. Folklore includes performing divination rituals using apples, nuts, and mirrors to glimpse fortunes for the coming year. Participants may carve pumpkins or kale into lanterns, an early form of jack-o’-lanterns, and tell stories by firelight. Traditions also involve wearing masks and costumes to confuse wandering spirits until dawn. Calan Gaeaf shares roots with the Gaelic Samhain and has experienced a revival in modern neopagan and cultural heritage events. Festivities often feature traditional music, dance, and storytelling, connecting participants with Welsh ancestral traditions.
