About this app

Experience Edo-period time with a "Clock of the Twelve Zodiac Animals."
EdoClock is a Japanese clock app that recreates the "Japanese time" that changes with sunrise and sunset, based on Japan's ancient timekeeping system, the "Variable Time System."

In the Edo period, time was not expressed using modern "1 o'clock, 2 o'clock," but rather using the twelve zodiac animals: Rat, Ox, Tiger, Rabbit, etc.

Furthermore, the "Variable Time System," which divided day and night into six parts each, created a unique sense of time that varied depending on the season and location, reflecting a life lived in harmony with nature.

EdoClock automatically calculates the "Edo time" for the day based on the sunrise and sunset times at your current location.

Experience the flow of time represented by the twelve zodiac animals in real time.
