National Bobblehead Day is observed worldwide every January 7 to celebrate collectible figurines known for their oversized heads that bobble when tapped. The holiday, launched in 2014 by the National Bobblehead Hall of Fame and Museum in Milwaukee, Wisconsin, recognizes the history and popularity of bobbleheads, which trace their origins back to 18th-century Asian nodding-head figurines. Initially popularized in the 1960s through Major League Baseball promotions, bobbleheads have since expanded to include a wide range of pop culture characters and notable figures. Celebrations often involve sharing photos of favorite bobbleheads on social media with the hashtag #NationalBobbleheadDay, purchasing new bobbleheads, or visiting the museum, which houses the largest collection of bobbleheads in the world. The inaugural celebration took place in 2015, and it has since become a cherished event for fans and collectors alike.
