National Underdog Day is celebrated on the third Friday in December, specifically on December 19 this year. This holiday focuses on appreciating and cheering for underdogs, individuals who are typically expected to lose or fail in competitions or events. The day encourages people to abandon the usual support for winning teams and instead celebrate the unsung heroes who often go unacknowledged. The concept of the underdog has deep roots in Western culture, illustrated by stories like 'David and Goliath' and figures such as King Arthur and Robin Hood. The term "underdog" originated in the 19th century, referring to a person working beneath a saw while building wooden ships. National Underdog Day was created in 1976 by Peter Moeller to honor these overlooked individuals in various fields, including sports and the arts.
