Old Japanese Clock

This app is a time converter between the current hour system and old Japanese hour systems. It can use two systems, a fixed hour system and a temporal hour system. The fixed hour system has six system types, engishiki, guchureki, semmyoreki, semi-engishiki, kanagoyomi and shichiyoreki. There were used mainly from the Nara era through to the Edo era (710–1872). The temporal hour system has seven system types, temporeki, koten, shaku-sun-bu (class 1 and 2), three-divided (class 1 to 3). There were used mainly in the late Edo era (1844–1872).

The app is useful when you will read a Japanese historical document, adjust a Japanese clock (Wadokei), mimic samurai life, and so on. If you need more information, please check the developer's website.
