Timekeeping is a universal human need, but did you know that the so-called “Lunar Calendar” isn’t actually lunar? In this episode of Unveiling the Orient, Hanfugirl and co-host Eustacia Tan explore how ancient civilizations, particularly in China and Japan, developed their calendars to balance agriculture, governance, and spirituality.

We break down why early societies needed calendars, the surprising accuracy of Chinese astronomical calculations, and how Japan adapted the Chinese system while introducing its own innovations. From the hidden solar roots of the 24 solar terms to the unexpected history of the seven-day week in East Asia, this episode challenges what you thought you knew about timekeeping.

Join us as we decode the fascinating interplay between astronomy, culture, and politics—because calendars aren’t just about marking dates; they’re about understanding civilization itself.
