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.
Quindecennial (15 years)
A quindecennial period represents fifteen years and is frequently used in demographic research, long-term economic modeling, and climate trend assessment. Because many social and environmental changes occur gradually, fifteen years provides a significant observational window for studying structural shifts in society, technology, or ecosystems. It is also a meaningful period in education and child development, roughly spanning the period from early childhood to adolescence. The quindecennial embodies the interplay between short-term generational patterns and broader, long-term societal transformations.
