About these units
Month (month)
A month traditionally reflects the lunar cycle, which lasts about 29.53 days (a synodic month). Ancient cultures used lunar months to track seasons, religious festivals, and agricultural cycles. In modern civil calendars, however, months are fixed lengths of 28–31 days to maintain alignment with the solar year. This creates a hybrid system: culturally grounded in the Moon, yet functionally tied to Earth's orbit around the Sun. Months remain one of the most intuitive time units for planning—budget cycles, billing periods, academic schedules, subscription systems, and medical dosing regimens all rely heavily on monthly intervals.
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.
