A time unit where 1 week = 7 days, originating from ancient Babylonian worship of seven celestial bodies (Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn), later adopted by Judaism and Christianity. Universally used today. China adopted the “week” system in the early 20th century as the basic cycle for work and rest (e.g., “two-day weekend”), making it a fundamental social time unit.
