Game Master Day (GM Day), observed each year on March 4th, honors the creativity and dedication of Game Masters and Dungeon Masters who guide tabletop role-playing adventures. The celebration first took shape in the RPG community in 2002, sparked by a forum post from a user known as Spunkrat and brought into wider recognition through the efforts of Mark Clover of Creative Mountain Games. The date was chosen as a playful call to “march forth,” and later came to serve as a fitting tribute to Gary Gygax, who passed away on that day in 2008.
