Millennia

A millennium is a unit of time equal to exactly 1,000 years (31,557,600,000 seconds using the Julian year). It is used in archaeology, geology, and history to describe long cultural and geological periods. The concept gained popular attention at the transition from the second to the third millennium AD (year 2000/2001). In astronomy, the precession of Earth's rotation axis completes one full cycle (the "Platonic year") in approximately 26 millennia.

Decades

The decade is a unit of time equal to exactly ten years, derived from the Greek deka (ten). While not a formal SI unit, it is widely used in demography, economics, history, and popular culture. In science, decade-scale processes are important in climatology (decadal temperature averages), epidemiology (ten-year cohort studies), and astrophysics (stellar variability cycles).
