Free Nine Star Ki chart

Your Nine Star Ki year star is the star of the solar year of your birth, which opens at 立春 (risshun) around 4 February: eleven less the digit sum of that year, brought down to one digit, so a birth on 1 February 1990 takes the star of 1989, 二黒, Two Black Earth. Your month star follows the solar months, which change at each 節 term, and your day star the Japanese day chart.

Enter your birth date, and your birth place if you know it, to see your three stars by the Japanese almanac rules: the stars of your solar year, month and day, your inclination palace, and your natal board with the year star in the centre, South on top.

About Nine Star Ki

Your Nine Star Ki chart is three stars, for the solar year, the month and the day of your birth: the year star is the star of the solar year, which opens at 立春 around 4 February and not on 1 January, the month star that of the 節 solar month, and the day star the Japanese day chart's. Born on 19 January 1989, before that year's 立春, the sample person falls in the year 1988 and takes the year star 三碧, Three Jade Wood, and the natal board sets that star in the centre of the Lo Shu square.

The square is Chinese and old; the system is Japanese, put together by 園田真次郎 (Sonoda Shinjirō) in 1924 from the direction lore of the Edo period.

How we compute it

The year from 立春 and the months from the 節 terms, placed in your birth time zone (your device's time zone when no place is given), and the day by the Japanese day chart with the leap rule of 園田真次郎 (1930). The birth time matters only for a birth on the day of a solar term; without it the almanac's whole-day rule decides.

Year star by year, 1930 to 2030

The Nine Star Ki year opens at 立春 (risshun), the moment the Sun reaches 315°, around 4 February. The moments below are in UTC, as our engine computes them: a birth before the moment, in the time zone of the birth, takes the star of the year before. Without a birth time, the almanacs count the whole day of 立春 in the new year.

Inclination (傾斜宮)

中宮 Chūgū

The year and month stars are the same, so the inclination falls on the centre; schools read it differently.

The natal board of a fictional person born on 19 January 1989 in Ann Arbor, Michigan, before that year's 立春, so in the solar year 1988. The year star 三碧 sits in the centre, South on top. Their month star is 三碧 too, so the inclination falls on the centre (中宮傾斜), the case the schools read differently. "Explore" opens the full chart: the year, month and day boards of any date, with the person's house and the directions the tradition names.
