Jozef's name day is observed on March 19th in Slovakia.
Jozef is a traditional masculine name common throughout Central and Eastern Europe, deriving from a Hebrew root meaning "He will add." Historically, its presence in the USA is tied to immigration waves, where it serves as a cherished link to European heritage. The name conveys a strong, traditionally sophisticated mood, suggesting reliability and seriousness. Its universal identity is strictly male, reflecting its deep historical use across Slavic regions. This variant remains less common than Joseph but is highly valued for preserving cultural integrity.
