Nine Star Ki — Your Main Star, and How to Read Directions
Nine Star Ki is an Eastern system centred on your Main Star, which is fixed by your year of birth. It reads your temperament, your cycles year by year and month by month, and your compatibility with directions. It has long been used as a reference when thinking about moving house, relocating a shop, or the direction of a business trip. In this corner, as well as readings for your Main Star and your Monthly Star, we show where your own star sits on the board this year and this month (its position).
On this site, planetary positions are calculated precisely, fortunes are read according to the established system of astrology, and the text is written by AI. Its strength is that there are no human calculation or interpretation errors.
Enter your date of birth
Your Main Star is fixed by your year of birth, and your Monthly Star by your month of birth. No time of birth is needed, so the result comes from the year, month and day alone.
An honest note on the foundations of Nine Star Ki
This site's horoscopes (Western astrology) are read by finding the actual positions of the celestial bodies by astronomical calculation. Nine Star Ki, by contrast, is not about the movement of stars: it is a system of the calendar and directions. Its foundation is the flow of time divided by the Start of Spring and the seasonal turning points, and the cycle of a “board” on which the nine stars are placed in a fixed order across the eight directions.
The foundation is different, but this site's stance of “showing the basis” is the same. In this corner too, how the stars are fixed, how years and months are divided, and how the board cycles are set out below as the basis of the calculation.

Reading your Main Star
This year's cycle
The year board is a board with the nine stars placed across the eight directions and the Centre. Each year, every star moves on by one. The red frame is where your Main Star sits this year.
This month's cycle
The month board changes at each seasonal turning point. With a shorter division than the year board, it is used to look at the movement of roughly the month in front of you.
Basis of the calculation
- The Main Star comes from the sum of the digits of your birth year. Add the digits of the year until you reach a single digit, and subtract that number from 11: the result is the star's number (if the answer is 10, read it as 1 White Water Star; if 11, as 2 Black Earth Star).
- The year changes at the Start of Spring. Not on 1 January: a person born before the Start of Spring (around 4 February) is calculated as born in the previous year. The time of the Start of Spring is found from the position of the Sun (ecliptic longitude 315 degrees).
- The month changes at the seasonal turning points. The division of the months is not the 1st of the calendar month, but the entries of terms such as Start of Spring, Awakening of Insects and Pure Brightness. The times of the entries are also found from the position of the Sun.
- The Monthly Star is fixed by the group of your Main Star and the seasonal month of your birth. The Main Stars are divided into three groups (1 White, 4 Green, 7 Red / 2 Black, 5 Yellow, 8 White / 3 Jade, 6 White, 9 Purple), and the star is set by the combination with your birth seasonal month.
- The cycle of the board follows a fixed order. On the year board, the star in the Centre moves on by one to a smaller number each year (after 1 comes 9), and on the month board it moves the same way at each seasonal month. The direction of each star is found by placing them along a fixed route, based on the star in the centre palace.
- Directions are measured from your home (or your company's base) as the centre. An auspicious direction is judged from the Five Elements relationship between the star currently in that direction and your own Main Star. The thinking in detail is written in “How to Read Directions” below.
Nine Star Ki is a guide for reading tendencies of temperament and timing. For big decisions at work, such as relocation or opening a business, please decide for yourself, weighing the figures and the actual circumstances together.
How to read directions — the basics of auspicious directions
Reading directions is the part of Nine Star Ki that has been used in connection with work. When you think about moving house, relocating a shop or office, or the destination of a business trip or inspection visit, you look at what star is currently in that direction. Here we set out only the basics.
The centre is “where you are now”
The basic rule is to measure directions from your own home as the centre. If you are reading for your work base, use your company's location as the centre. Draw a line from the centre on a map and check which direction the destination falls in. Directions are divided into eight (North, Northeast, East, Southeast, South, Southwest, West, Northwest). In the division used by this corner's boards, the four cardinal directions — North, East, South, West — are each 30 degrees wide, and the corner directions — Northeast, Southeast, Southwest, Northwest — are each 60 degrees wide.
What counts as “auspicious”
Judge by the Five Elements (Wood, Fire, Earth, Metal, Water) relationship between the star currently in the destination direction and your own Main Star. Directions where the other star is in a generating relationship to yours, and directions where a star of the same element is present, are candidates for an auspicious direction. By contrast, the direction where 5 Yellow Earth Star sits (the Five Yellow killing direction) and the direction exactly opposite it (the Dark Sword killing direction) have traditionally been considered best avoided, on both the year board and the month board. On this page's boards, those two are marked.
Points to note when you use it
A direction is only one piece of material for a decision. We do not recommend deciding a big step such as a relocation or opening a business on direction alone. First settle the practical facts of a candidate place — rent, customer base, ease of getting there — and then use direction as a final point of comparison. That order is close to how business owners who have long used directions have actually used them. Directions are also said to mean less for short moves nearby, and are generally read for moves over a certain distance (moving house, or a business trip with an overnight stay, for example).
