The Woodstock Music & Art Fair—informally, the Woodstock Festival or simply Woodstock—was a music festival, billed as “An Aquarian Exposition: 3 Days of Peace & Music”. It was held at Max Yasgur’s 600-acre (240 ha; 0.94 sq mi) dairy farm in the Catskills near the hamlet of White Lake in the town of Bethel, New York, from August 15 to August 18, 1969. Bethel, in Sullivan County, is 43 miles (69 km) southwest of the town of Woodstock, New York, in adjoining Ulster County.
During the sometimes rainy weekend, 32 acts performed outdoors before an audience of 400,000 young people. It is widely regarded as a pivotal moment in popular music history. Rolling Stone listed it as one of the 50 Moments That Changed the History of Rock and Roll.
The festival is also widely considered to be the definitive nexus for the larger counterculture generation.
