JIKANKEI “FUJYO JIHOU” / 時間系不定時報

JIKANKEI is a software art. The word JIKANKEI is the time system, and FUJYO JIHOU is gradually changing time in Japanese. We are living in one of 24 local time zones by modern universal system, also are involved into one global time by the Internet. JIKANKEI shows the sunrise, the sunset and the sun direction times. This is a primitive time idea, but more personal. JIKANKEI does not express scientifically accurate data. It is only an art work. Linger in the morning brightness, in the afternoon glow, and enjoy the gradually changing seasons on this globe. JIKANKEI is like fictions or poems. It is useless in this pursuit of profitable computer society. I hope you will realize your standing place on this globe and feel the atmosphere of the Earth. The author makes no warranties to your physical and/or mental damages.

The basic idea of "JIKANKEI FUJYO JIHOU" is before Westernized Japanese Clock System (until 1873). Probably it was the most popular time system in the world. I believed your ancestors lived in the similar JIKANKEI time. I just did not know the histories well. FUJYO JIHOU divides daytime to six equal periods which an angular unit to 30 degrees is measured along the celestial equator. When it is equinox one of periods is almost two hours. However It is changed by seasons, summer time is longer and winter time is shorter. The each divided points were named to the 6 directions of zodiac symbols in day time and the 6 directions of symbols in evening, such as U (卯: pronounced "wu" rabbit, the sunrise. six gongs: ake mutsu), TATSU (辰: dragon, 30 degrees from the sunrise / about two hours form the sunrise. five gongs), MI (巳: pronounced "me" snake, 60 degrees from the sunrise / about four hours from the sunrise. four gongs), and UMA (午: "wuma". horse, 90 degrees. noon. nine gongs), HITSUJI (未: sheep. 120 degrees. eight gongs), SARU (申: monkey. 150 degrees. sevent gongs), TORI (酉: rooster. 180 degrees. six gongs: kure mutsu). JIKANKEI also shows one twelfth of daytime and one twelfth of evening time for the understanding of differences between twenty fourth even divided modern clock system.

JIKANKEI displays angles of the Sun and local times of cities and places on the Earth. When the Sun transits on divided 30 degrees, JIKANKEI plays a signal of MIDI sound which is made by the text of Sun date of the places. Mac version shows a full screen of Google MAPS's satellite images on the background.

JIKANKEI takes sunrise and sunset data of the specific place from US Naval Observatory Date Services by longitude and latitude through Internet. The development of JIKANKEI was started in 2002. It had been suspended for some years for the Internet data problems. However the development was restarted in September 2012.
