Castilla–La Mancha Day, observed in the autonomous community of Castilla–La Mancha in Spain, is celebrated every May 31. This holiday commemorates the first session of the Cortes of Castilla–La Mancha, which took place on this date in 1983. The region, known for its historical significance, includes the city of Toledo, which became an important cultural center during the Reconquista. The day is marked by various festive events such as flag raising ceremonies, parades, concerts, exhibitions, fairs, sports competitions, and award ceremonies. Each year, the celebrations are hosted in a different city or town within the community. As it is an official holiday, local schools, universities, government offices, and some businesses close for the day, with public transport operating on a holiday schedule.
