Zu Chongzhi on Calendar and Superstition

	A calendar should be based on astronomy rather than schools of mysticism, and so it does not matter whether it corresponds to divination and superstition. These prophecies may seem accurate for a time, but in the long term they cease to have any relevance, therefore your subject puts no trust in them. —Zu Chongzhi (429 - 500)—
