What is the name of the chronicle of Sadakan, Sadawoo, and Sadamoto? Is there any such name in Japanese chronology?

Yes, for example, Sadakan was the Japanese year from April 15, 859 to April 16, 877, and the emperors of Japan in this period were Emperor Seiwa and Emperor Yosei in the Heian period.

Japan began to learn from China's use of the nianhua system at the time of the Dahua Reform, but the difference was that it did not necessarily change its nianhua at the time of the change of monarchs as China did, and it was not until December 3 of the fifth year of the Meiji era (January 1, 1873) that it switched to the Western sun calendar
