June 15 Holidays

Global Wind Day was established by the European Wind Energy Association and the Global Wind Energy Council to celebrate wind energy as a renewable resource — wind now provides more than 7 percent of global electricity generation and is the fastest-growing energy source on Earth. Magna Carta Day marks June 15, 1215, when King John of England sealed the Magna Carta at Runnymede — the charter that established for the first time that the king was subject to the rule of law, laying the foundation for constitutional governance. National Prune Day celebrates the dried plum that California’s Santa Clara Valley once produced in such quantity that it made the state the world’s leading prune supplier — a fruit whose reputation for digestive benefits has been confirmed by modern nutritional research. Beer Day Britain was established on June 15 to mark the date in 1215 when the Magna Carta guaranteed the standardization of ale measures across England — the same document, one clause lower, that protected civil liberties. Wind, a charter, a wrinkled plum, and a standardized pint.
