Semmyō calendar
Semmyō calendar (宣明暦, Semmyō-reki), also known as Semmei-reki or Xuanming li, was a Japanese lunisolar calendar (genka reki).[1] It was used from the late-9th century to the late-17th century.[2]
History[change | change source]
The Semmyō-reki or Semmei-reki system corrected errors in earlier calendars which were developed in China.[3] It was the work of Shibukawa Shunkai and Shikokawa Kōkyō.[4]
The earliest record of this calendar is in the 8th month of the 3rd year of Jōgan (861) during the reign of the Emperor Seiwa.[5]
