Crossword Puzzle Day

Celebrated on 12/21/2026

Quick Fact

Crossword Puzzle Day is celebrated on December 21, the anniversary of the first published crossword puzzle, which appeared in the New York World in 1913. The inventor, Arthur Wynne, originally called it a 'Word-Cross' puzzle.

Origins and Establishment of Crossword Puzzle Day

Crossword Puzzle Day commemorates the publication of the first crossword puzzle on December 21, 1913, in the New York World newspaper. Created by British-born journalist Arthur Wynne, the puzzle was initially shaped like a diamond and lacked the black squares that are common today. Wynne called it a 'Word-Cross' puzzle, but a typographical error changed the name to 'Cross-Word' and eventually 'crossword.' The holiday was informally established by puzzle enthusiasts and media to honor the enduring popularity of crosswords.

Evolution and Modern Commemoration

Crossword puzzles quickly became a staple in newspapers worldwide, with the first crossword book published in 1924. The puzzle's popularity soared during the 20th century, leading to specialized publications like the New York Times crossword, which began in 1942. Today, Crossword Puzzle Day is celebrated by solving puzzles, hosting competitions, and sharing favorite puzzles online. Digital platforms have expanded access, allowing millions to enjoy crosswords on apps and websites. Many newspapers and puzzle clubs run special events or release themed puzzles on this day.
