Old Japanese Clock
Life with Various Hour Systems
$3.99 · Designed for iPad
Also Included In
This app serves as a time converter between the current hour system and old Japanese hour systems. It offers two options: a fixed hour system and a temporal hour system.
The fixed hour system includes six different types: Engishiki, Guchureki, Semmyoreki, Semi-Engishiki, Kanagoyomi, and Shichiyoreki. These systems were primarily used from the Nara era through to the Edo era (c. 710–1872).
On the other hand, the temporal hour system encompasses seven types: Temporeki, Koten, Shaku-Sun-Bu (Class 1 and 2), and Three-Divided (Class 1 to 3). These were predominantly used during the late Edo era (1844–1872).
This app proves invaluable when reading Japanese historical documents, adjusting Japanese clocks (Wadokei), or recreating the lifestyle of ninjas and samurais, among other apps. For more detailed information, please visit the developer's website.
