Imbolg, observed on the first day of February, is the second of the four ancient yearly Celtic Festivals, representing the advent of the traditional agricultural year. There are four great Feast Days of the Celtic Year:
Samhain - the Celtic New Year (Halloween) celebrated on November 1st
Imbolg - the Feast of the Goddess Brigit on February 1st
Beltane – festival honouring the beginning of summer
Lughnasadh - the harvest festival and last feast day in the year which falls on August 1st
February 1st is also the feast day of St Brigid. Brigid is both a Celtic Goddess and a Christian Saint, in what is a clear merging of pagan and Christian traditions.
