Draft:Mario Day

Mario Day (often formatted as MAR10 Day, also known as National Mario Day ) is an annual celebration themed around the Mario franchise. The event takes place on March 10, since the first three letters of March and the number 10 side-by-side resembles the word "Mario". It was first officially established by Nintendo in 2015 when they posted a video on their official YouTube channel. Since then, Nintendo has launched multiple events surrounding the Mario franchise each year on March 10, including discounts on currently-available games or special announcements.

Mario Day and its name was originally coined by fans in 2014 in which fans would celebrate the day on social media using the hashtag "#Mar10". Nintendo would respond to this the year after when they began to embrace the event by celebrating it themselves.
