Imbolc

Imbolc or Imbolg, also called (Saint) Brighid's Day, is a Gaelic festival marking the beginning of spring. Most commonly it is held on 1 February, or about halfway between the winter solstice and the spring equinox. Historically, it was widely observed in Ireland, Scotland and the Isle of Man. It is one of the four Gaelic seasonal festivals—along with Beltane, Lughnasadh and Samhain. Christians observe it as the feast day of Saint Brighid, especially in Ireland.
