  • The clock's calendar is designed to remain accurate for at least 14,400 years.

History

The creation of Jens Olsen's World Clock was a lifelong ambition for its creator. Jens Olsen, a self-taught locksmith, began drafting the plans in 1927. Following his death in 1945, a team of horologists and engineers continued the work, ensuring that his precise calculations were realized. The clock was officially inaugurated on December 15, 1955, by King Frederik IX of Denmark. Its construction was funded through a national collection, reflecting the pride the Danish public felt toward this complex mechanical achievement. The clock has since undergone periodic maintenance to ensure its gears continue to move with the extreme precision Olsen originally intended.

Cultural significance

Jens Olsen's World Clock represents a significant period in Danish scientific history, symbolizing the transition from traditional craftsmanship to highly calculated mechanical engineering. It is a cultural icon in Copenhagen, housed prominently in the City Hall to signify the city's commitment to progress and timekeeping. The clock is not merely a tool for telling time; it is a monument to the human desire to map the heavens and understand our place in the universe. It remains a source of national pride and a primary example of Danish design and technical excellence in the mid-20th century.

Geography and landscape

The clock is situated in the heart of Copenhagen, specifically within the grand Copenhagen City Hall (Rådhus). The surrounding area is characterized by the historic urban landscape of the city center, including the bustling Rådhuspladsen (City Hall Square).
