Jōkyō

Jōkyō (貞享^?) was a Japanese era name (年号, nengō^?, "year name") after Tenna and before Genroku. This period spanned the years from February 1684 through September 1688. The reigning emperors were Reigen-tennō (霊元天皇^?) and Higashiyama-tennō (東山天皇^?).

Subsequently, the power to create a calendar shifted to the shogunate and the authority of the Imperial calendar was diminished after 1684. In that year, the astrology bureau of the Tokugawa bakufu created a "Japanese" calendar which was independent of Chinese almanacs.
