The Euro Disney Resort officially opens with its theme park Euro Disneyland; the resort and its park's name are subsequently changed to Disneyland Resort Paris.

Disneyland Park, originally Euro Disneyland Park, is a theme park found at Disneyland Paris in Marne-la-Vallée, France. The park opened on 12 April 1992 as the first of the two parks built at the resort. Designed and built by Walt Disney Imagineering, its layout is similar to Disneyland Park in California and Magic Kingdom Park at Walt Disney World in Florida. Spanning 56.656 ha —the second largest Disney park based on the original, after Shanghai Disneyland—it is dedicated to fairy tales and Disney characters.

Disneyland Paris is an entertainment resort in Marne-la-Vallée, France, located about 32 kilometres east of Paris. It encompasses two theme parks, seven Disney-owned hotels, two convention centers, a golf course, an arena, and a shopping, dining and entertainment complex. Opened on 12 April 1992, the resort is operated by Disney Experiences, a division of the Walt Disney Company.

April 12 is the 102nd day of the year in the Gregorian calendar; 263 days remain until the end of the year.
