9 Star Ki calendar – day Stars and start of months

This annual calendar with daily Stars for the Star 8 year of 2019 serves as an example and for your easy reference. This calendar can be used for purpose of 9 Ki Divination 九宮占卜 or Nine Star Ki Astrology 九星命理.

If you are a practitioner of Flying Star Feng Shui 風水飛星派, you’ll be equally working with annual-, monthly- and daily Luoshu for purpose of house divination. Different day calendars for 9 Stars may return different day Stars for the exact same Solar date.

It has been like this since Nine Star Ki Astrology 九星命理 was introduced to the West by Michio Kushi in the late 1970s.

Today, we distinguish between the more popularly known Nine Star Ki Astrology on the one hand, then 9 Star Ki Divination on the other hand.

How to read the day Ki Star calendar
Use the day Star calendar in your 9 Ki Divination 九宮占卜 work, to forecast real (news) events and your personal life progression.

Table itself explains how to read this calendar, while I’ll add some slight considerations while you read on.

Here proposal for day Ki Stars is courtesy Danny van den Berghe’s professional Four Pillars & Feng Shui 4.2 software, which I like to rely on for its accuracy:

    • Formulae for day Ki Stars are quite involved. This software bases its day Ki calendar on formulae given in the only surviving Chinese Classic on the subject “Precious Sea Classic” – Bao Hai Jing 寶海經.
    • It is the only software to my knowledge to embed Swiss Ephemeris, so that it gives starting moments for year, months, days and hours faithful to the ecliptic.
    • Consequently, it returns the correct year-, month-, day- and hour Pillars for purpose of Four Pillars of Destiny Bazi 八字算命, accurate to Solar timing.
    • It automatically calculates for Equation of Time.
    • It can calculate for Day Light Saving Time (optional).
    • It allows to select your Time Zone, Time Meridian, coordinates.

A bit more on daily Stars
Most software will be based in uniform lookup tables – often acquired from literature – but which tables are meant to give starting dates for months by approximation only.

If a software algorithm relies on generic tables, it will each time start a particular month on the same date for any given Solar year.

If it lets the month of August start on the 7th, it will give the month Pillar in Bazi as Shen Monkey, even if for certain years, the month starts only on the 8th.

Your Chinese horoscope may be now a few Heavenly Stems and Earthly Branches off, until actually all Four Pillars in your Bazi birth chart may come out wrong, which is the same as where you would be reading the birth chart of another person, still regard it your own.

To each time let a Solar month start on the same Solar date, would only imply that, on its orbit around the Sun, planet earth would reach the exact same degree of arc on the ecliptic on the exact same Solar date.

Ascending and descending day Stars
While not touching on the highly complicated formulae, Solstice days are pivotal in day Star calculations.

Day Stars will run in ascending order for approximately 180 days, then have a change-over moment, after which day Stars will descend another approximately 180 days.

The change-over moment from ascending to descending day cycles vice versa, occurs on the Solstice moment on the Solstice day, while the Solstice day will produce 2 day Stars.

While then the Solstice day starts in a certain Star, upon the Solstice moment, the day will proceed in a different Star. These 2 Stars will Add to Ten.

More specifically, from the Solstice moment on the December Solstice day onward, daily Stars will ascend up until the June Solstice, while from the June Solstice moment onward, daily Stars will descend until the December Solstice.

Try not to say ‘Summer Solstice’ or ‘Winter Solstice’, if only because your fellow practitioner on the other Hemisphere, might not know ‘where you’re coming from’.
Equinoxes and Solstices occur for the planet as a whole.

Consequently, the Chinese Solar calendar starts 3, 4, or 5 February at
Li Chun 立春, for both the Northern Hemisphere and the Southern Hemisphere.

Further approaches would then involve the 24 Solar Terms 二十四)節氣, exactly when a Yang Wood-Rat day (Jia-Zi 甲子) occurs within a certain Solar Term, and the day formula involves exceptions to the rule and exceptions to exceptions to the rule, but it is not unimportant to note that earlier conventions where change-over was given as either 2 consecutive Star 9 days or 2 consecutive Star 1 days may have been flawed.

Annual-, monthly- and daily Stars in 9 Star Ki
Let’s build up to an annual-, monthly- and daily Luoshu for a 7 Metal day in an 8 Earth month, in a 9 Fire year.

9 Star Ki Astrology - year Star, month Star, day Star - Heluo Hill

You may use annual-, monthly- and daily Luoshu in 9 Ki Divination for purpose of forecasting:

    • Real (news) events, earthquakes, accidents, labor strikes, assaults, missing persons.
    • Personal life progression, planning of your initiatives, do’s & don’ts.

Side note on personal forecasting
Each one of us obtains 3 Stars in Nine Star Ki Astrology, but there have been 2 conventions.

This means that any one of us may receive 2 sets of ‘3 Stars’, while the crux of the matter is in the third Star.


    • 9.4.1 (Japanese convention, third Star is not time based)
    • 9.4.5 (Third Star is day Star of birth, so it is time based)

Each time, the first Star is obtained from year of birth, the second Star from month of birth.

The third Star in the so-called Japanese method is not time based, it is not the day Star of birth. If here, for example, your Stars are 9.4.1, then ‘1’ is not your day Ki of birth, so that you’ll not involve this third Star in your 9 Ki Divination.

Same person can be born on a 5 Earth day, so that this can be used as the third Star. If the third Star is decided by the Star for day of birth, it is time based, so that you may indeed use it in your forecasting through 9 Stars and Luoshu.
