Kyureki Taizen (Kadokawa Sofuia Bunko)

[Machine Translation] The "lunar calendar" has been familiar to the Japanese people since ancient times and is still closely related to events in modern times. The book covers all aspects of the Japanese calendar, including how leap months are determined, local calendars of the Edo period and how they are viewed, the 24 solar terms and 72 horary signs that represent subtle changes in the seasons, the relationship between the 12 signs of the zodiac and the five elements of the yin-yang theory, the twelve zodiac signs and the Big Dipper, 28 astrological signs that represent a constellation around the celestial sphere, the six solar terms and nine stars used to determine good and bad fortune, and more. The book is a complete reference. This is a book you will want to have on hand, both as a dictionary and as a fun read.
