About these units

Century (century)

A century equals 100 years and is a major unit of historical, demographic, and civilizational analysis. Historians frequently divide narratives into centuries to highlight long-term transformations—technological revolutions, empire rises and falls, or artistic movements. Sociologists study century-scale changes in population, urbanization, and cultural evolution. Although human lifespans rarely exceed one century, this unit is large enough to encompass sweeping societal changes, making it ideal for macrohistorical studies.

Millennium (millennium)

A millennium is 1,000 years, a timescale that allows examination of civilizations, languages, religions, and climate eras. Millennia encompass major epochs such as the rise of agriculture, the development of writing, the spread of major religions, and industrialization. From the perspective of Earth science, a millennium is still a short interval—volcanoes, glaciers, and tectonic changes unfold over tens of thousands to millions of years—but it provides a useful bridge between historical and geological time. Culturally, millennia also carry symbolic weight, such as the transition to the year 2000, which triggered widespread reflection on long-term human progress.
