If you don’t know why today we celebrate “Mario Day” around the world, we’ll tell you everything you need to know about it like who created it and why.

March 10th (aka MAR10 Day) is here, and you know what that means - it’s time to celebrate everyone’s favorite mustached plumber with some epic Nintendo Switch deals.

Wahoo! March 10 is National Mario Day, which honors one of the most iconic video game characters ever created… Mario. The date, when written as “Mar10,” kind of resembles the name “Mario” — making it an oh-so-fitting day to honor everyone’s most favorite plumber.
