Mart's name day is November 10 in Estonia.
Mart presents as a very rare given name in the USA, typically functioning as an informal reduction of names such as Martin. Its meaning and origin are generally inherited from these longer forms, suggesting a history rooted in Germanic naming conventions. The name’s tone is decidedly strong, direct, and pragmatic, lacking softer connotations. While globally associated with the masculine gender, its sparse usage in the US means it has little established cultural footprint there. It conveys an immediate sense of brevity and efficiency.
