Did You Know?
The seven-day week has Babylonian origins and was later reinforced by the Roman calendar and religious traditions. It is the only calendar unit that does not align with any astronomical cycle - a day is one Earth rotation, a month approximates the Moon's cycle, and a year is one orbit around the Sun. But a week? Purely a human convention, consistent for over 2,000 years.
