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.

Octennial (8 years)

An octennial period covers eight years and is significant in political and historical contexts—especially where term limits or cycles operate in eight-year increments, such as two consecutive four-year political terms. The octennial cycle also appears in meteorology, where certain oscillations such as ENSO (El Niño–Southern Oscillation) exhibit approximate multi-year frequencies. Its moderate length makes it useful in demographic and cohort studies that compare long-term stability with relatively short generational intervals.
