Litha, (leetha) also known as Midsummer or the summer solstice, is the longest day of the year. It’s also a minor sabbat for witches, pagans and Wiccans. The holiday marks the height of the Oak King or solar god’s power. Litha is all about abundance, growing crops, and welcoming the first day of summer. Pagans celebrate the sabbat with bonfires intended to bring luck and protect the coming harvest.
