National Keaton Day is celebrated annually on April 15, honoring the Keaton family name, which is notably associated with actors Michael and Diane Keaton, as well as the silent film star Buster Keaton. The name "Keaton" has its origins in the Old English county of Ketton, believed to mean 'place of hawks.' Ketton, a landlocked settlement in Rutland, England, is recognized as the fourth-largest settlement in its county and has a history linked to cement manufacturing and limestone quarries. The holiday encourages appreciation of the Keaton name and its cultural significance, although specific customs or activities associated with the celebration are not detailed in the text. The name is also used as a given name, making it gender-neutral.
