为什么一周有七天，而不是五天或十天？
Why is a week seven days, not five or ten?
七天周制源自古巴比伦，与月相周期（约28天分四段）和宗教传统有关，后被多文明沿用。它并非自然节律，而是人造时间单位。
The seven-day week came from Babylon, tied to lunar phases (about 28 days in four) and religious tradition, later adopted by many civilizations. It is not a natural rhythm but a human-made time unit.
