Lughnasadh Gemstones Lughnasadh, also known as Lammas, lands on the 1st of August and is the 7th stop on the Wheel of the Year. Marking the midway point between the Summer Solstice and the Autumn Equinox, Lughnasadh is the first of 3 harvest festivals. Thanks are due for the abundant summer crops and the first grain harvest as we honor Lugh, the Celtic Sun King and God of Light. The energies of summer are shifting and the sun begins to wane. This is a time of gratitude and transformation.
