On July 17, 1955, Disneyland opened its gates for the very first time. While this was a momentous and historic occasion for Disney, the day did not go quite as planned. Disneyland opening day was referred to by cast members as “Black Sunday” due to all of the problems experienced at the park. | Disney | History | Disneyland
Disneyland Opening Day Ad Each year around July 17th many arguments start over whether the 17th or the 18th is the true opening day of Disneyland. This ad seems to prove that the 18th should be considered the true opening day, with a large banner reading Opens Monday July 18. The ad is from a San Diego newspaper (either the Union, the Evening Tribune or even the Sun) and most likely ran on Saturday. The ad copy is very entertaining.
