Not a typical holiday, Sadie Hawkins Day was the invention of cartoonist Al Capp. Capp invented a day in fictional Dogpath, U.S.A., when unmarried women could chase the man they wanted to marry. If caught, the bachelors would have to walk down the aisle. A modified version of Sadie Hawkins Day, one in which women asked men for a date but didn't require their hands in marriage, was first celebrated on Wednesday, November 9, 1938. Today, it's usually celebrated on the Saturday that falls closest to that date.
