The feast of St. Brigid falls on February 1st, the day of her death and the traditional 1st day of spring in Ireland. Some speculate that Brigid was also a pagan goddess and so coincedentally, Feb. 1st is a pagan/Wiccan "cross quarter day" (or holy day) referred to as Imbolc and is related to St. Brigid in 1 way or another. So the feast day for Brigid the Saint and Brigid the Goddess is Feb. 1st either way.
