On this day in 1985, Disneyland began operating seven days a week throughout the year. Up until that time, Disneyland would often be closed Mondays and Tuesdays in the off season, including early spring, fall, and winter. The closure days were used for park upkeep and attraction maintenance. Interestingly, Magic Kingdom and EPCOT at Walt Disney World have always been open daily year round, even before 1985.
