Monmu period

The adoption of the Sexagenary cycle calendar (Jikkan Jūnishi) in Japan is attributed to Empress Suiko in 604; and this Chinese calendar continued in use throughout the Mommu period. In 645, the system of was introduced. However, after the reign of Emperor Kōtoku, this method of segmenting time was temporarily abandoned or allowed to lapse. This interval continued during the Monmu period. Neither Empress Mommu's reign nor the Monmu periodization are included in the list of nengō for this explicit duration of time, which comes after Suchō and before Taihō. In the post-Taika or pre-Taihō chronology, the first year of Emperor Monmu's reign (文武天皇元年 or 文武統皇1年) is also construed as the first year of the Mommu period (文武1年). ==Non-nengō period==

Non-nengō periods in the pre-Taihō calendar were published in 1880 by William Bramsen. :*Hakuchi, February 650–December 654. :**Non-nengō dating systems :*Shuchō, July–September 686. :**Non-nengō dating systems :*Taihō, March 701–May 704. Nengō were not promulgated (or were allowed to lapse) during the gap years between Hakuchi and Shuchō, and in another gap between Shuchō and Taihō. ==Events of the Mommu period==
