9 Star Ki calendar – day Stars and start of months

Here 9 Stars day Ki calendar applies to the Star 4 year of 2023, while it is equally in use for purpose of 9 Ki Divination 九星占卜, Nine Star Ki Astrology 九星命理Four Pillars of Destiny Bazi – 子平八字算命 and Flying Star Feng Shui 風水飛星派.

If you are a practitioner of 9 Stars 九星 and Luoshu 洛書, then besides annual- and monthly Luoshu, you may want to include daily Stars for divination purposes. You may as such have come across different day calendars to 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 久司道夫 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 for purpose of forecasting real (news) events and personal life progression 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, past-present-future by the hand of annual- and monthly Luoshu, then if you will, you may want to include 9 Stars daily Luoshu.

Table itself explains how to read this calendar, while I’ll add some slight considerations as 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
Now that some day Ki Star calendars will be based in uniform lookup tables, this is where often you will see it stated that ‘a’ year in the Chinese Solar calendar is to start on February 4th. This is meant as an an approximation at best. 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 return the month Pillar in Bazi as Shen Monkey, even if for certain years, the month starts on only the 8th.

Your Chinese horoscope may be now a few Heavenly Stems and Earthly Branches (Ganzhi 干支) off, until actually all Four Pillars in your Bazi birth chart may come out faulty, which is the same as where you would be reading the birth chart of another person, then 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 for purpose of Nine Star Ki.

Day Stars will run in ascending order for approximately 180 days, then have a change-over moment, after which day Stars will descend for 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 then 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 relate as to ‘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 now that 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 a Solar year on 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 it was given change-over 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 – randomly – build up to an annual-, monthly- and daily Luoshu for a 7 Metal day in an 8 Earth month, in for the purpose an exemplary 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, as you screen your news channels.
    • Personal life progression, planning of your initiatives, do’s & don’ts past-present-future.

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