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.
Day (Sidereal) (d (sidereal))
A sidereal day is the time Earth takes to rotate exactly 360 degrees relative to the distant stars—about 23 hours, 56 minutes, 4 seconds. In contrast, the solar day is slightly longer because Earth advances in its orbit each day and must rotate extra degrees for the Sun to appear in the same position in the sky. Sidereal days are fundamental to astronomy: telescopes use sidereal time to track stars, which appear in the same position in the sky at the same sidereal moment each night. This unit anchors astronomical observation to the cosmos rather than to the Sun.
