One of the most remarkable and overlooked facts of history is that our seven-day week, which structures the lives of billions of people, has its origins firmly rooted in ancient astrology. It stands as perhaps the single most successful and widely adopted astrological concept of all time, even though its origins are now largely forgotten.
In this video, I explain the precise astronomical and astrological reasoning for the seven-day week. We'll review the seven traditional planets—the Sun, Moon, Mars, Mercury, Jupiter, Venus, and Saturn—and demonstrate how their ancient order directly corresponds to the sequence of the days of the week that we still use today.
We'll also touch on the historical timeline, tracing the system back to the Hellenistic tradition of astrology around the 1st century BCE and noting its mention in the work of the 2nd century astrologer Vettius Valens. From there, we'll see how this calendrical system spread from the West through the Silk Road, becoming integrated into Persian, Indian, and eventually East Asian traditions as well.
This is a fundamental piece of astrological and cultural history, and understanding it is key to appreciating the deep impact that astrology has had on the world.
