National Rubber Ducky Day is observed worldwide every January 13, celebrating the iconic rubber duck toy that has been a part of Western pop culture for over a century. The holiday likely connects to the character Ernie from Sesame Street, as this date is noted as Rubber Duckie’s birthday in the 1972 Sesame Street Calendar. Participants typically enjoy bubble baths with their favorite rubber ducks, and many engage in activities such as purchasing new rubber ducks, watching Sesame Street episodes featuring Ernie’s beloved toy, and attending rubber duck races that raise money for various non-profits. The rubber duck, originally designed in the 1940s by sculptor Peter Ganine, has evolved from a solid chew toy to a floating bath companion, inspiring water play that aids in children's development. Enthusiasts often collect various novelty rubber ducks, and the day encourages sharing photos on social media using specific hashtags to promote the celebration.
