Kansei calendar
From Wikipedia, the free encyclopedia
Kansei calendar (寛政暦, Kansei-reki) was a Japanese lunisolar calendar (genka reki).[1] It was published in 1797.[2]
The Kansei-reki system was the work of Takahashi Yoshitoki[3] and Hazama Shigetomi.[4]
Takahashi and Hazama used Western astronomy studies to modify the traditional calendar.[4]
