This clock has the system based upon the unequal temporal hour, used in Edo era in Japan about 300 years ago. A criteria is set at the time 36 minutes before sunrise ('Ake-Mutsu'), the other criteria is set at the time 36 minutes after sunset ('Kure-Mutsu'). Two periods between these two criteria are divided into 6 parts equally, as each of them are called 'Toki'. Every 'Toki' are divided into four parts further. This is a clock for ancient natural life - awake and start working at sunrise, stop working and sleep at sunset.

The velocity of the single arm of this clock is varied by day and night, and by seasons, though the dial of this clock is divided equally. It is different from the conventional analog clock whose arms always move at constant velocity. The upper half of the dial of this clock represents daytime, and the lower half represents nighttime. The left end of the dial is Ake-Mutsu, the right end is Kure-Mutsu respectively.

You can see the conventional times of sunrise and sunset, Ake-Mutsu and Kure-Mutsu, by tapping 'status' button at the bottom of the clock. These times are based upon your device's local time zone.

位置の設定について–Location setting

This clock calculates the times of sunrise and sunset based upon location (longitude and latitude) and season (date) automatically. Initial setting of the location of this clock is set to Tokyo. You can change the location setting by tapping 'location' button. In 'Location' panel, you can set location by selecting cities all over the world, or set longitude and latitude, or use your location data from your device's location functionalities (ex. GPS).

時報機能について–Time signal

At every 'Seikoku' (the arm at the center of every 'Toki' as outermost divisions of the dial), bells are rung. At around midnight, Seikoku of '子' of new year's eve, bells are rung 108 times as 'Joya-no-kane' (to remove 108 earthly desires and welcome new year purely) as same as most of temples in Japan.
