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).

Weeks

The week is a unit of time equal to exactly seven days (604,800 seconds) with no direct astronomical basis. Its origin is cultural and religious, rooted in ancient Mesopotamian astronomy that associated each day with one of seven celestial bodies visible to the naked eye. The seven-day week spread globally through the Roman Empire and later through Christianity and Islam.
