Comic Sans Day, celebrated on July 1, is an unofficial holiday that invites people to embrace the quirky, playful font known as Comic Sans. Created in 1994 by Vincent Connare for Microsoft, Comic Sans was inspired by comic book lettering and designed to be friendly and approachable. Despite its widespread use, the font has sparked controversy among typographers and designers due to its informal nature. Comic Sans Day encourages fans and critics alike to use the font without judgment, celebrating its unique charm and the spirited debates it continues to inspire.
