Hōreki 1(宝暦元年,Hōreki 1?); October 27, 1751: The new era of Hōreki (meaning "Valuable Calendar" or "Valuable Almanac") was said to have been created to mark the death of the retired Emperor Sakuramachi and the death of the former ShogunTokugawa Yoshimune.
The previous era could be said to have ended and the new era is understood to have commenced in Kan'en 4, on the 27th day of the 10th month; however, this nengō was promulgated retroactively. The Keikō Kimon records that the calendar was amended by Imperial command, and the era was re-named Hōreki on December 2, 1754, which then would have become 19th day of the 10th month of the 4th year of Hōreki.[1]
