mario day 2026 mar10 history events nintendo celebrations
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.
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. It was simply a display of love for the 1981 arcade character from Donkey Kong. It spread naturally online, mixing nostalgia with creativity.
Nintendo noticed the excitement and tweeted acknowledgements in 2015, such as wishing Smosh Games a “Happy Mario Day.” By 2016, it became official with promotions, eShop deals, and events. Highlights include 2023’s “Every Day Is a Mario Day” motto, a Nintendo NY party with Mario, Luigi, and Ryan Kaji, and in-game perks.
Now, MAR10 Day features sweepstakes, store events at Nintendo NY and SF, Mario Kart World tournaments, and promotions for the 2026 Super Mario Galaxy Movie, which releases on April 1. This celebration honors the 40th anniversary of Super Mario Bros. Fans can play games, collect merchandise, or visit SUPER NINTENDO WORLD. It’s a party for everyone!
