Gihō calendar

Gihō calendar (儀鳳暦 Gihō-reki), also known as Yi-feng li, was a Japanese lunisolar calendar (genka reki).^[1]

History

The calendar was created in China. It was first used in the Rintoku era during the Tang Dynasty.^[2]

The Gihō-reki system was brought from Korea to Japan in Yi-feng era (676-678) of the reign of Emperor Gaozong of Tang. This calendar corrected errors in the Yuan-jia li (Genka calendar) which was developed in China.^[3] For a short time, both Genka and Gihō calendars were in use.^[4]
