National Mini Golf Day is celebrated every second Saturday of May in the United States. This day encourages people to visit mini-golf courses with family and friends to enjoy the game and showcase their putting skills. Miniature golf originated in 19th century Victorian Scotland, initially created to allow women to participate in golf. The game features shorter courses with the same number of holes as traditional golf, often incorporating themed obstacles to enhance the experience. Over time, mini-golf has gained popularity and recognition as a sport, with standardized rules established in the early 1960s. Celebrating this day typically involves playing mini-golf and enjoying the social aspects of the activity.
