About Mario Day
Mario Day is an unofficial holiday celebrated every year on March 10, a date that spells out the iconic name when written as MAR10. The day honors Nintendo's beloved mustachioed plumber, who first debuted in 1981 and has since become one of the most recognizable characters in entertainment history, with Nintendo officially embracing the occasion since 2016 with special game releases and promotions.
