July 17 is a very big day at Disneyland. Each and every year on this date the park celebrates its birthday. The “Happiest Place on Earth” officially opened July 17, 1955, so it has been open for 62 years.
Special souvenirs that aren’t available every other day of the year will be available on this special day. There’ll be a lot of excitement. The anniversary is a very big day for Disneyland and a very busy one, as well. So if you are there, have patience as major attractions like It’s a Small World will have big lines.
