Tuesday Trivia - Disneyland Operations

For most of the first 30 years of Disneyland's operation (1955 - 1985), the park only operated 5 or 6 days each week as the park was closed every week on Mondays, and often Tuesdays, for general refurbishments, cleaning and overall park care. It was on February 6, 1985 that the park began operating 7 days per week and has been open every day, all week long every week, since then (with only a couple of single-day closures - following the events of 9/11 back in 2001 and a "day of preparation" in advance of the 50th Anniversary celebrations back in 2005)
