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

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]
