Mario Day History: From Fan Holiday to Official Nintendo Bash

Every March 10, fans around the world celebrate Mario Day, a fun reference to Nintendo’s plumber hero. The date “MAR10” cleverly looks like “Mario” in all caps, bringing joy for over a decade. What started as grassroots fun has turned into a must-do event for Nintendo.

Fan Origins Spark the Fun

Super Mario fans first noticed the “Mar10” magic between 2010 and 2012, though its exact origins are unclear. Fans celebrated it informally by playing classic games like Super Mario Bros., hosting costume parties, or sharing memes. There was no involvement from Nintendo.
