Lughnasadh is generally celebrated on August 1, or during the first full moon of Leo, depending upon the Pagan tradition involved. In prehistoric times, it was a Gaelic festival that marked the beginning of harvest season. Lammas is another name for it, and it is also referred to as the "first harvest", the second harvest is the autumnal equinox and the third is Halloween. Our ancestors had festivals and carnivals back in the day, to celebrate a great harvest and to trade. The practice of holding fairs and carnivals late in the summer came from Lammas festivals. The celebrated God is Lugh, whose name literally means "light", and friendly competitions and mock battles symbolized Lugh, or light, triumphing over barrenness and darkness.Hope you had a very happy Feast of Lugh!
