In modern Wicca, the summer solstice sabbat is Litha.
Litha is one of the eight festivals commonly placed on the Wiccan Wheel of the Year. It marks the summer solstice, usually around June 20–22 in the Northern Hemisphere, when daylight reaches its annual maximum. Many celebrations emphasize the Sun, fertility, abundance, bonfires, flowers and the turning point after which daylight gradually begins to diminish.
The name can sound ancient, but its modern Wiccan use is relatively recent. It was popularized in the 20th-century development of neopagan festival calendars and draws on the Anglo-Saxon month names recorded by the eighth-century writer Bede. Litha is therefore not simply an unchanged survival of one ancient holiday. Wiccan traditions vary: some call the observance Midsummer, while modern Druids may use Alban Hefin. Beltane is the earlier cross-quarter festival associated with the beginning of summer, whereas Litha is the solstice itself. Imbolc and Samhain belong to different points in the seasonal cycle.
