Beltane is a cross-quarter day, marking the midpoint in the Sun's progress between the spring equinox and summer solstice. Beltane is the second principal Celtic festival, the other being Samhain. Beltane traditionally marks the arrival of summer, Samhain marks the arrival of winter.
Old Celtic tradition says that many people would rise at the first light of dawn to go outdoors and gather flowers and branches to decorate their homes. Beltane marks the return of vitality, of passion. Ancient Pagan traditions say that Beltane marks the emergence of the young God into manhood. Stirred by the energies at work in nature, he desires the Goddess. They fall in love, lie among the grasses and blossoms, and unite. In old Celtic traditions it was a time of unabashed sexuality and promiscuity where marriages of a year and a day could be undertaken.
I bet that isn't something you knew before! Does that mean that May 2nd was divorce day? The day that these "marriages" or I think they're called "handfasting" now end?
Happy May Day and Happy Beltane!
