This episode explores the origin of the seven-day week from an astronomical, historical, and cultural perspective. We discuss how Hindu astronomers identified grahas and how the Brihat Parasara Hora Shastra outlines a method to establish the seven-day week. We also look at how the idea of the seven-day week originated in ancient Babylon and was adopted by other civilizations. Bibliography: Satyabhama A. (2014).
